BMS Phase II student’s 3D models are winners
Martin Skrodzki, BMS Phase II student and member of the FU Berlin’s Mathematical Geometry Processing group, was part of the winning team in the FU Berlin’s "Research to Market Challenge 2017". His team, Double Cover, was awarded first prize in the category “Cultural & Social” for its business model to make artistic and aesthetic geometric models available for education.
Created using sturdy, metallic-looking paper, the cut-outs for the models can be produced in large numbers using a laser cutting technique. The models are then put together by the users themselves and depict mathematical geometries with so-called multiple coverings. These are geometric analogies to the weaving process used in the production of cloth. By introducing multi-coverings, the models become both more stable and mathematically interesting. The models presented depict platonic solids, double covered, but the method can be applied to any geometrical model. Potential customers for Double Cover’s winning idea include teachers, science workshop organizers and private individuals. The other team members are the former BMS vice chair and head of the Mathematical Geometry Processing group Prof. Dr. Konrad Polthier, technical staff member Ulrich Reitebuch and student assistant Kevin Guo.
The “Research to Market Challenge” is a competition for research-based product and business ideas and is open to members or alumni of the FU Berlin, among others. As well as prize money in the sum of 1500 euros, the team has been offered the chance to take part in a one-day workshop on business model development, coaching on how to successfully present their idea, and personal feedback by experts.
No sooner had Martin accepted this prize with his team on 18 July 2017, than he and some members of his research group were awarded with another prize! On 10 August 2017 in Tokyo, Japan, the winners of this year’s Asian Digital Modeling Contest (ADMC) were announced: Martin, Konrad, and Ulrich were jointly awarded one of the two ADMC2017 Awards for Excellence for their model “Chladni Towers”.
The aim of the ADMC is to encourage the creation of three-dimensional mechanisms and objects in innovative environments via 3D printing technology. The competitors were asked to submit an original design that could be created using a 3D printer. Out of 27 competitors, eleven finalists were invited to present their designs at the 2017 Asian Forum on Graphic Science in Tokyo. Upon announcing “Chladni Towers” as one of the winning designs, the jury explained its choice: "The form is constructed from a layered Chladni figure, which is derived from physical phenomena. Visualization of sound is often performed by two-dimensional figures, but by using a layered structure, additional dimension is expressed in the height direction and the vibration of sound is expressed in a 3D space. The idea is novel and the realized form is elegant. This is a splendid work that visualizes invisible physical phenomena.”
As a member of the Mathematical Geometry Processing group at the FU Berlin, Martin is currently working on his PhD under the supervision of the former BMS vice chair Prof. Dr. Konrad Polthier. Martin's research interests include the acquisition of point sets via 3D-scanning as well as their processing. With regards to efficiency, he is interested in nearest-neighbor algorithms and corresponding data structures.
Many congratulations to Martin and the other members of his team for their success!
BMS welcomes a student delegation from Atlanta
On Tuesday 23 May 2017, the BMS welcomed a delegation of 20 undergraduate students and three faculty members from Morehouse College and Spelman College, two American universities situated in Atlanta, Georgia. This event aimed to give the visiting students and faculty a chance to connect with their counterparts in Germany, and gain first-hand exposure to prospective careers and research opportunities in the field of mathematics.
BMS Deputy Chair, Prof. Dr. John Sullivan, began by giving a presentation about the BMS, its PhD Program, and about the mathematics landscape in Berlin in general. This was followed by talks from three BMS Phase II students, who each presented their own research projects. Patrick Gelß, based at the FU, gave a talk on “The tensor-train format and its applications - Modeling and analysis of chemical reaction networks, catalytic processes, fluid flows, and Brownian dynamics”. Ana Djurdjevac, also based at the FU, presented her research on “Random PDEs on evolving hypersurfaces”. Finally, using material from his PhD project, Carlos Echeverría Serur, based at the TU, gave a talk entitled “On the solution of linear systems arising from Shishkin mesh discretizations”. Carlos said he hopes that all the talks will encourage some of the American students to come to Berlin for their graduate studies.
Following the BMS presentations, the delegation then visited the TU Berlin's 3D LAB. Afterwards, the American students and faculty were given the chance to interact informally with BMS students, faculty and staff over lunch in the BMS Lounge.
This event was part of the STEM LAUNCH Study Tour of Germany organized by Cultural Vistas, a non-profit organization that facilitates connections between American and international students, academics and professionals. Through a two-week professional and cultural tour of Berlin and Munich, this study tour aims to encourage students from Georgia-based historically black colleges & universities to consider adding an international context to their educational and career paths.
20th BMS Kovalevskaya Lunch
Each semester, the BMS designates one of the BMS Friday Colloquia as the Sonia Kovalevskaya Colloquium. This lecture, named after the pioneering Russian mathematician, features female mathematicians, both senior and junior, who are regarded as successful role models. The BMS Kovalevskaya Lunch takes place prior to the main lecture and is an event held exclusively for women at the BMS.
On 2 June 2017, the 20th BMS Kovalevskaya Lunch took place with Prof. Sujatha Ramdorai as the twentieth special guest invited to share her experience as a woman mathematician with twenty participants from the BMS. In celebration of this milestone, everyone in attendance was given a small gift from the BMS in the form of a USB stick.
Sujatha Ramdorai is an algebraic number theorist and, over lunch at the Urania Berlin, she shared the story of her desire to study mathematics and outlined her career success to date, which includes being a member of the Scientific Advisory Council to the Prime Minister of India for a period of five years. Sujatha is currently a professor of mathematics at the University of British Columbia in Canada.
The BMS Kovalevskaya Lunch, held once a semester since 2007, aims to give female students the opportunity to talk to an outstanding female mathematician and to exchange experiences as women in the field of mathematics. At this informal event, students have the chance to discuss the issues that directly impact female mathematicians and their careers, such as job opportunities, parenthood and work-life balance. Phase I student Yingying, who took part in the Kovalevskaya Lunch for the first time, said that the meeting with Sujatha gave her more motivation to continue doing mathematics and to contribute to the support of women in this field. She added that she was grateful to have been given the chance to meet Sujatha in person.
Previous Sonia Kovalevskaya Colloquium guest speakers can be found on this page of our website.
The BMS is committed to providing an outstanding environment where women are able to thrive in mathematics. In 2016, the BMS student body was over 30% female, but the goal of the BMS is to achieve a 50% representation of women among its students. As well as the Kovalevskaya Lunch event, the BMS strives to provide positive role models for women via the BMS faculty and postdoc faculty members, BMS mentors, board members, guest speakers and visitors too. In addition, the BMS awards the Hilda Geiringer Scholarship to outstanding female PhD students in recognition of their achievements to date and to support their future mathematical research endeavours. Hilda Geiringer’s daughter, Magda Tisza, validated the efforts of the BMS in fostering women mathematicians with her comment: "The stellar record of some of your scholarship selections is impressive."
Jürg Kramer appointed EMS Committee Chair of Education
The BMS would like to congratulate Jürg Kramer on his appointment as the European Mathematical Society's Committee Chair of Education. Kramer, who is the vice chair of the BMS and professor for mathematics at the HU Berlin, took over as chair from Günter Törner (U Duisburg-Essen) whose term of office ran from 2010 to 2016.

Looking back at the BMS 10th Anniversary celebration
The Berlin Mathematical School is ten years old! Established in 2006, the BMS has flourished into a highly successful graduate school currently consisting of more than 200 students and boasting a PhD alumni community of over 210 academics and professionals. In ten short years, the BMS has welcomed aspiring young mathematicians from over 50 countries, reached its goal of 50% international students, and achieved a ratio of 31% female students.
From 17 to 18 November 2016, the BMS held a colorful program of events in celebration of its tenth birthday. The festivities began in advance at the TU Berlin Mathematics Library on the evening of 16 November with a BMS Welcome Reception combined with the opening of "Art on Board: the Beauty of Math". This art exhibition showcases early mathematical prints by Bernar Venet and aquatints from the "Concinnitas Portfolio" and will run until 28 February 2017.
On the morning of 17 November, the main event took off in the Audimax at TU Berlin. Seven talks were given by distinguished speakers active in different BMS research areas. Each plenary speaker was introduced by two BMS students from the same area of research. Prior to each talk, several BMS students and one of the guest speakers gave very enjoyable and moving vocal and instrumental musical performances.
Over half of the BMS student body attended the main event to take advantage of the opportunity to learn from outstanding mathematicians from all around the world. In between the scheduled talks, there was time to socialize with the seven guest speakers, around forty external guests, and over sixty BMS faculty, staff and alumni. At the end of the first day, the BMS student representatives held an (unexpectedly) fun "Math Quiz", which was followed by a buffet reception in the early evening.
The chance to network prior to the main event was not lost as BMS students were invited to take part in a World Café. This event was designed to offer current students the opportunity to meet and chat to BMS alumni and postdocs about various topics such as PhD research, applying for postdoc positions and job availability in the private sector.
In recognition of ten years of the BMS, some of the opening speeches were made up of just ten sentences. The BMS Chair, Günter M. Ziegler, presented ten sentences composed by a BMS alumna in which she emphasized the more profound values of a university education. Opening speeches were also given by Christian Thomsen (President, TU Berlin), Peter A. Frensch (Vice President for Research, HU Berlin), Peter-André Alt (President, FU Berlin) and Steffen Krach (Berlin's State Secretary for Science).
In his closing speech at the end of the two-day celebration, Professor Ziegler held fast to his newly invented tradition and gave ten sentences of thanks to everyone involved in organizing, presenting, participating, supporting and attending the BMS 10th Anniversary events. In a recent interview, he said "The BMS has achieved so much in ten years: it has changed the mathematical landscape in Berlin, brought international students from the world over to this city, and has created a concept and given a face to studying mathematics in Berlin."
The Berlin Mathematical School would like to extend its heartfelt thanks to everyone who has helped to make the past ten years so successful. We are very excited about the next ten years, so watch this space!
Humboldt Prize & Marthe Vogt Award for Mira Schedensack
On 17 October 2016, at the opening ceremony of the 2016/17 academic year, five students and young scientists of Humboldt University Berlin (HU) were awarded with the Humboldt Prize 2016 in honor of their excellent scientific work. One of the recipients was BMS alumna Mira Schedensack who was recognised for her outstanding doctoral thesis. No sooner had Mira accepted one of the Humboldt dissertation prizes, than she was awarded with another prize! On 2 November 2016, the Forschungsverbund Berlin e.V. (FVB) honored Mira with the Marthe Vogt Award. The FVB was just as impressed by her excellent dissertation entitled "A class of mixed finite element methods based on the Helmholtz decomposition in computational mechanics".
Problems from mechanics are often solved using mathematics. For example, if a building engineer wants to know how a balcony will deform under a heavy load, mathematicians can describe this by means of partial differential equations. Usually, the solutions cannot be calculated exactly, so they are approximated using numerical methods. Thus the reliable numerical approach of such solutions plays a fundamental role in the mechanical application. For engineering practice, such procedures have to be easy to implement, deal sparingly with computer resources, and provide the most accurate results possible. For more than 50 years, mathematicians around the world have been researching extensively on how to improve this method, but in this area there was not much new to discover. The best minds had already developed the most efficient methods. Then Mira took up the challenge with an excellent dissertation that presented fundamentally new and sensationally easy-to-implement procedures. In her PhD thesis, Mira abandons the conventional approach to the approximation of PDE solutions and makes use of the characterization of the derivative as a conservative vector field via a Helmholtz decomposition, which breaks down an unstructured vector field into a gradient and a rotation field. Mira explained "There were no simple methods to solve problems of higher order. Whether or not I would find practical procedures was not initially clear, but the theory fascinated me." Mira wanted to do something completely new and not simply improve old methods. "That would certainly have been safer. My approach was risky, but I found it exciting" she said.
As a BMS scholarship holder, Mira did her PhD under the supervision of BMS faculty member Prof. Dr. Carsten Carstensen. She completed her doctorate at the HU in 2015 and graduated with summa cum laude. Currently, Mira is a postdoctoral researcher at the University of Bonn's Institute for Numerical Simulation and also a guest lecturer in the working group Numerical Mathematics at the HU.
The Humboldt Prize is an annual award given to outstanding students and young scientists whose final theses are deemed examples of outstanding scientific work. All prizes are awarded by the university president at the opening ceremony of the new academic year. The dissertation prize comes with a monetary award of 3000 euros. The FVB awards the Marthe Vogt Award annually to one outstanding young female scientist who is active in the same field as any of the eight research institutes represented by the FVB. This prize is also endowed with 3000 euros.
Mira, congratulations on your achievements!

Klaus Tschira Award for BMS alumna Ágnes Cseh
Ágnes Cseh, BMS alumna and doctoral graduate of TU Berlin, was one of six recipients of the 2016 Klaus Tschira Award for Achievements in Public Understanding of Science (Klaus Tschira Preis für verständliche Wissenschaft).
The Klaus Tschira Foundation (Klaus Tschira Stiftung) established this nationwide competition in 2006 with the aim of fostering public appreciation of natural sciences, mathematics and information technology. The challenge presented to young scientists is to write an article about their research and PhD thesis in a way that is understandable to the scientifically interested, but non-specialist person. This year, the jury chose the six prizewinners from 168 applicants in a three-phase evaluation procedure.
For her PhD thesis entitled “Complexity and Algorithms in Matching Problems under Preferences”, Ágnes studied the 'stable marriage problem', which has been in the research spotlight for over 50 years. She succeeded in broadening the scope of this well-known problem in graph theory, which is traditionally illustrated by a mathematical modeling of partner finding. In her winning article, “Marriages are made in calculation” (Heiraten nach Plan), Ágnes describes this model, which has been frequently applied in the business world for decades for the purpose of bringing together different stakeholders in the most optimal way. The wide range of possible applications of this theory includes sports fixtures, living kidney donations, online auctions and the distribution of student dormitories. Ágnes illustrated the existing mathematical model using human partner selection, but her enhanced model is universally applicable.
Ágnes was presented with the Klaus Tschira Award on 6 October 2016 at the University of Heidelberg's historical Alte Aula and is the fourth member of the BMS alumni to receive this prize. Tim Conrad was a recipient in 2009, Jannik Matuschke in 2014 and Timo Berthold in 2015. The award came with prize money in the sum of 5000 euros. In addition, all winning articles will be published in their original form in the popular science magazine “bild der wissenschaft”.
As a BMS student, Ágnes won the “First Berlin Science Slam” in Cairo in April 2012 and, in November of the same year, she won the first prize in the “Best Master/Diplom Degree” category at the TU Berlin's Dies Mathematicus. In 2013, she was awarded the Clara von Simson Prize for her outstanding master's thesis entitled “Stable Flows”. Ágnes completed her PhD at TU Berlin in 2015 under the supervision of BMS faculty member Prof. Dr. Martin Skutella, and graduated with the honor of summa cum laude. After a research stay at the ICE-TCS (Icelandic Centre of Excellence in Theoretical Computer Science) in Reykjavík, she is now a post-doc at the Hungarian Academy of Sciences in Budapest.
Ágnes, congratulations on your success!
