The 6th Heidelberg Laureate Forum (HLF) took place at Heidelberg University from 23 to 28 September 2018. The HLF is a networking event for mathematicians and computer scientists from all over the world and is organised annually by the Heidelberg Laureate Forum Foundation (HLFF).

200 young scientists from 60 nations were successful in convincing the foundation's scientific advisory board of their outstanding academic abilities to secure a place at this event, where they were given the chance to interact extensively with 32 Laureates of mathematics and computer science. The Laureates are the winners of some of the most prestigious awards in those two fields: the Abel Prize, the Fields Medal, the Nevanlinna Prize and the ACM A.M. Turing Award.

There are several stages in the career of a young researcher during which they may apply to attend the HLF: undergraduate; graduate (in the PhD phase); or postdoc. Four BMS students were selected to attend the HLF this year: Tatiana, Josué, Giulia and Jorge © Heidelberg Laureate Forum Foundationthe Phase I student Tatiana Levinson, and three Phase II students Giulia Codenotti, Jorge Alberto Olarte and Josué Tonelli Cueto. The BMS students took the opportunity to converse with their fellow participants and with the Laureates in between attending the various talks, workshops and events.

The 7th HLF will take place in September 2019 and the application process will begin on 15 November 2018.

The HLF was initiated by the Klaus Tschira Stiftung (KTS), a German foundation which promotes natural sciences, mathematics and computer science, and the Heidelberg Institute for Theoretical Studies (HITS). The Forum is organized by the HLFF along with KTS and HITS. It is strongly supported by the award-granting institutions: the Association for Computing Machinery (ACM: ACM A.M. Turing Award), the International Mathematical Union (IMU: Fields Medal, Nevanlinna Prize), and the Norwegian Academy of Science and Letters (DNVA: Abel Prize). A longer news article in English can be found on the HLF website.

Dirk Becherer and Martha Nansubuga, © privateIn August 2018, BMS faculty member and HU professor of mathematics, Dirk Becherer, and BMS Phase I student, Martha Nansubuga, visited the African Institute for Mathematical Sciences in Ghana. Dirk was invited to give a three-day seminar on "Stochastic Control for Markets with Finite Liquidity" and Martha was one of the participants. Of the approximately 45 master level students who attended the seminar series, 12 were women, and in addition to the new cohort of AIMS students, several MPhil and PhD students and research visitors from the AIMS Research Centre also took part.

After the seminar series had ended, Martha scheduled a meeting with the AIMS students a few days later in order to give a one-hour presentation about the BMS. She first described the structure of Phase I and Phase II, then talked about the math landscape in Berlin, and followed that with information about the BMS study program, including soft-skills seminars, What is...? seminars and BMS Friday lectures. She emphasized how important the latter two events are for coming into contact with other fields of mathematics and the people active in them. Martha then added a personal touch by telling the students about her life as part of the BMS family, the various social activities organized by the student representatives, as well as the BMS Buddy Program, which for Martha has been a great success as her buddy is still happy to offer help whenever she needs it.

She also told the AIMS students about three members of their alumni who found their current success by doing a PhD in stochastics via the BMS. They are Victor Fenou Nzengang, BMS Alumnus and now a postdoc at the University of Freiburg; Klébert Kentia Tonleu, BMS Alumnus and now a senior consultant in Frankfurt; and Ludovic Tangpi, a former BMS Phase II student, who is now an assistant professor at Princeton University. She also took the opportunity to mention that one can experience the BMS by applying to a BMS Summer School too, which a friend of hers from AIMS South Africa did. Her application was successful and she came to Berlin for the 2017 BMS Summer School in "Probabilistic and Statistical Methods for Networks". Martha's presentation included a long and lively discussion, and at the end she handed out informational material and promotional items from the BMS.

Dirk Becherer, Martha Nansubuga, and Olivier Menoukeu Pamen © privateMartha combined her activities for the BMS with a four-week research stay working with Dr. Olivier Menoukeu Pamen, the German Research Chair at the AIMS Ghana Research Centre. She studied and discussed deterministic and stochastic maximum principle problems with Dr. Pamen and his research students, attended the SAFIM workshop in Accra, and took part in other scientific activities with the AIMS students. Martha stayed on the AIMS Ghana campus in Biriwa, and lived and dined with the students, staff and lecturers at the institute, who took every chance to ask her questions about the BMS and life in Berlin. In their free time, her hosts took her on trips to the beach, into town for dinner and to the Kwame Nkrumah Mausoleum in Accra. Martha enjoyed her experience at AIMS and was happy to be able to share her knowledge with its ambitious and talented students. Her own personal piece of advice for them with regards to studying mathematics was to strive to "understand simple things deeply".

Dirk and Martha's activities at AIMS Ghana were made possible through the "Berlin-AIMS Network in Stochastic Analysis", whose goal it is to foster scientific exchange between mathematicians in Berlin and Ghana. The collaborating partners are the HU Berlin, WIAS and AIMS Ghana and this network is part of a DAAD-funded program that supports university cooperation with AIMS (Hochschulkooperationen mit dem AIMS). In coordination with Dr. Pamen, Dirk and Martha will soon welcome some ambitious students from the AIMS research center to Berlin for a reciprocal visit. Naturally, these young researchers are very much looking forward to experiencing the wide mathematics environment in Berlin and, in particular, are keen to learn more about the activities of the BMS community during their stay.

The BMS would like to thank Dirk and Martha for their efforts on behalf of the BMS, and thank you to Dr. Pamen for the hospitality he gave them!

AIMS was founded in South Africa in 2003 as a pan-African center providing advanced, broadly applicable mathematical skills to talented students recruited from all over the continent. Since 2011, AIMS has opened additional centers in Senegal, Ghana, Cameroon, Rwanda and Tanzania.

© DFG, source: http://www.dfg.de/download/pdf/foerderung/programme/exzellenzstrategie/exstra_entscheidung_exc_180927.pdfOn 27 September 2018, a press conference to announce the decisions about the new Clusters of Excellence to be funded within the framework of the German Research Foundation’s (DFG) Excellence Strategy was live-streamed from the Wissenschaftszentrum Bonn.

On the basis of previous international review sessions, members of an international committee of experts appointed by the Joint Science Conference (GWK) deliberated on a total of 88 proposals on 25 and 26 September. The final selection was made in the Excellence Commission, where members of the committee of experts convened with federal and state government ministers responsible for science and research.

From the 88 proposals, 57 were successful nationwide, and the Berlin Mathematics Research Centre “MATH+“ was one of seven proposals from Berlin selected to be funded by the DFG as a Cluster of Excellence for the next seven years. From 1 January 2019, MATH+ will be established as a new joint cluster of the three Berlin universities, Freie Universität Berlin, Humboldt-Universität zu Berlin and Technische Universität Berlin, as well as Weierstrass Institute for Applied Analysis and Stochastics (WIAS) and the Zuse Institute Berlin (ZIB).

The Berlin Mathematical School will be part of MATH+ and will continue as a graduate school for mathematics within this new framework. This success will give the BMS the opportunity to extend its current activities, for example to continue supporting the BMS Dirichlet Postdoctoral Fellowship.

Congratulations to all members of the BMS and to all those actively involved in planning and composing the MATH+ proposal!

On Friday 13 July 2018, the BMS Certificate Ceremony took place in the Goethe Saal at Harnack-Haus in Berlin's leafy residential district of Dahlem.

After the final BMS Friday Colloquium of the summer semester given by Prof. Dr. Monique Laurent (CWI, Amsterdam), BMS students, friends, family and BMS faculty, staff and guests joined together to celebrate the academic achievements of 21 BMS Phase I graduates and 83 BMS Phase II graduates.

The certificate ceremony began with a welcome speech by the new BMS Chair, Prof. John M. Sullivan, who began by congratulating the recent graduates on their success. He then reported that, in the 12 years since its foundation, the BMS has celebrated the success of 300 PhD graduates, and remarked that the internationality of BMS students continues to have a great effect on the math landscape in Berlin. In his short speech, Prof. Günter M. Ziegler, the outgoing BMS Chair and new President of FU Berlin, highlighted the internationality of the BMS management too and, in a quote by Hemingway, he encouraged the new graduates to be prepared for whatever luck the future might bring.

Monique Laurent returned to the stage to award Certificates of Completion to those students who completed Phase I during the past two years by passing the BMS Qualifying Exam. She then awarded Certificates of Distinction to the Phase II students who completed their PhDs in the same period. The ceremony also included musical performances by the duo "Wild Strings", a violinist and guitarist who perform their own improvised versions of classical music pieces.

After receiving their certificates, the BMS graduates gathered in the garden for some photographs and then everyone joined them outside to enjoy the celebratory reception under the warm evening sun.

Patrick Morris, a Phase I graduate from the UK who is now halfway through Phase II, was grateful to the BMS for organizing such a special celebration and giving graduates the opportunity to invite friends and family along. Through the presentation of Phase II dissertation titles, he said his guests were able to get a real impression of where all his hard work can lead to. Antje Bjelde, a BMS Phase II graduate from Germany who is now working as a freelance researcher, said that seeing a "Dr." title before her name, as it was displayed on the presentation, is still a surreal feeling.

Phase I graduates Dragana Radojičić from Serbia and Shimaa Elesaely from Egypt both travelled back to Berlin from abroad to attend the ceremony. Dragana said: "It was a great pleasure to attend the ceremony and I was very happy when I got an invitation. I finished Phase I of the BMS program two years ago, and since then I do not miss an opportunity to visit Berlin and meet friends I made here. In addition to meeting dear people from the BMS, these events are always nicely organized with a wonderful atmosphere and great food." Shimaa remarked: "What I liked was to see old friends again and to celebrate my success with them. During the ceremony I enjoyed the music, and afterwards I enjoyed the delicious buffet and socializing with friends, professors, students and staff."

Almost 150 people attended on the day and we would like to thank everyone who joined us in celebrating the academic success of our students. Not all of our graduates were able to attend the ceremony, so we would like to take this opportunity to congratulate everyone. Well done, we are very proud of you all!
