We are delighted that the BMS-BGSMath Junior Meeting took place at the University of Barcelona this year from 05 to 07 September after it had been postponed due to the ongoing Corona pandemic. Around 80 participants attended this year’s meeting in Spain. Prof. John M. Sullivan of TU Berlin represented the BMS as one of its Deputy Chairs. The Berlin Mathematical School (BMS) and the Barcelona Graduate School of Mathematics (BGSMath) alternatively organize regular meetings as both schools share their ambitions to conduct excellent doctoral and postdoctoral training programs. They cooperate in developing initiatives to promote the mobility of and exchange between students and faculty members through events like the Junior Meeting, joint Summer Schools, mutual visits by advanced students and postdocs of each institution, and other scientific activities. The Junior Meeting also aims to intensify current collaborations and create new links between the two schools. The scientific sessions were focused on different areas of Mathematics, trying to cover a wide range of topics and be of interest to all the participants. No previous background in a specific area was required to attend and understand the talks.

Following the usual rotating principle, the next BMS-BGSMath Junior Meeting will be held in Berlin in 2023.

BMS PhD student Sofía Garzón Mora described her impressions of the meeting:

“During the past 5-7th of September, the BMS-BGSMath Junior Meeting took place at the historical building of the University of Barcelona. Almost 50 participants from Berlin attended this short yet very fruitful workshop, where the Barcelona organizers and participants joyfully welcomed us. The schedule was packed with plenary talks by invited senior speakers and junior researcher talks, distributed in parallel sessions by content throughout the day. This diversity in mathematical subjects was the perfect opportunity to attract those in the audience with an affinity towards some topics and invite more in-depth discussions and questions. The coffee and lunch breaks were an important addition to the program, where we enjoyed local delicacies while continuing to get to know our colleagues. Last but not least, the evening allowed us to delight ourselves with Mediterranean food during the Conference Dinner and go for a relaxing swimming session at the Barceloneta beach, where we enjoyed the last days of summer under the scorching Spanish sun.

Adios Barcelona, we already look forward to participating in the next junior meeting.”

After a two-year break, MATH+ and its Graduate School, the BMS, were finally able to honor its graduates and recent BMS alumni with a festive certificate ceremony in the beautiful and traditional Leibniz-Saal of the Berlin-Brandenburgische Akademie der Wissenschaften (BBAW). Almost 140 members and guests followed the invitation and enjoyed a wonderful afternoon and long overdue get-together.

The afternoon started at 13:00 with the BMS PhD seminar “What is…?“. PhD student M. Levent Dogan introduced the topic of the following MATH+ Friday colloquium on “P, NP, and Probabilistically Checkable Proofs”, held by Irit Dinur of the Weizmann Institute of Sciences. The presentations were part of the 2022 nationwide event series of “The 7 Greatest Adventures of Mathematics” that focuses on the description of the seven Millennium Prize problems presented by seven German mathematical research institutions. The recordings of the presentations on "P versus NP" are available on the MATH+ YouTube channel.

At 16:00, MATH+ Chair Christof Schütte welcomed everyone to the Certificate Ceremony and gave a laudation of the MATH+ Dissertation Award winners from 2020 and 2021, a prize first initiated in 2020. Dr. Josué Tonelli-Cueto (2020), Dr. Lena Walter (2021), and Dr. Paul Hager (2021) were present to proudly receive their Dissertation Award certificates. Congratulations to all of them! Also, congratulations to Dr. Leon Sering (2020) and Dr. Ander Lamaison Vidarte (2021), who unfortunately couldn’t participate in the ceremony.

The Berlin Mathematics Research Center MATH+ is offering support for mathematicians from academic institutions in Ukraine that have recently left the country due to the ongoing Russian attack on Ukraine. The special fellowship program is an offer for refugees from Ukraine in the Berlin area that hold a master’s degree or higher in mathematics or a closely related field and have pursued mathematical research at a university or other academic institution in Ukraine within the past year (exceptions to this one-year rule may apply due to parental leave etc.). The aim of the program is to enable refugees to continue their research and start new collaborations at one of the mathematics institutes of the universities FU Berlin, HU Berlin, and TU Berlin, as well as the non-university institutes Weierstrass Institute for Applied Analysis and Stochastics (WIAS) and Zuse Institute Berlin (ZIB).

Usually, selected BMS applicants are invited to travel to Berlin to participate in the BMS Days – an important annual BMS event to recruit promising young scientists. However, due to the ongoing pandemic, the BMS Days took place online for the second time, from 21-22 February 2022.

This year’s online format presented new activities in a mixture of zoom talks, poster sessions, and virtual interactive encounters via the meetingland event platform. The purpose of the BMS Days was only for the applicants to get to know the BMS. The invited applicants were introduced to the graduate school’s program and had the opportunity to ask questions about living and studying in Berlin.

40 Phase I and 4 Phase II applicants from 15 countries attended in different time zones and therefore in two groups. On the first day, the students received an overview of the BMS program and the students’ life in Berlin. This was followed by group meetings where applicants had the chance to ask the BMS students, faculty members, and office staff questions in a smaller, more informal settings. To conclude the day, the BMS Student Representatives arranged an online game. The second day gave an insight into different mathematical research topics. The lectures were given by Claudia Schillings (currently at the University of Mannheim), who will start as the new MATH+ professor at FU Berlin in March, on “Uncertainty Quantification and Inverse Problem” and Thomas Walpuski of HU Berlin on “Invariants of manifolds arising from partial differential equations”. Both talks were preceded by the student-run “What is…?” seminars to give the audience a basic introduction. Afterwards, the applicants had the chance to meet BMS postdocs and PhD students in a poster session and learn about their research experiences.

As always, the BMS Days were followed by the BMS Student Conference from 23-25 February. The main goals of the Student Conference are to connect both current and prospective students and help prospective students get to know the mathematical landscape in Berlin and the social environment at the BMS. Additonally, two invited talks were given by Chris Wendl (HU Berlin) and Peter Schröder (Caltech).

Despite the great virtual experiences and opportunities to get to know each other, the BMS hopes to welcome the next group of applicants in person again in 2023.

Each year in November, the BMS students elect a new team of BMS Student Representatives for one year. We are delighted to announce this year’s new team: Sophia Bugarija, Apratim Choudhury, Fawzy Hegab, Lea Strubberg and Bálint Zsigri.

The new team will start their term in December, while the recent BMS Student Representatives - Gerard, Saraí, Owen, Duc, Nicolas and Berk - are busy organizing the BMS Student Conference 2024 (to take place on 21 - 23 February 2024).

In general, the BMS Student Representatives have two main tasks: They serve as a contact between the BMS students and the BMS administration and help BMS students to connect with each other.

In addition, they represent the BMS students on various official committees and can voice students' concerns and suggestions there. The representatives try to notice needs and also organize an annual survey to find out about the issues and concerns of the BMS students.

To help BMS students get to know each other and provide opportunities for networking, they offer a wide range of activities like
• organizing social events,
• running a peer-mentoring program,
• connecting new students with those of similar academic interests,
• organizing a Career Day with BMS alumni once a year

At the end of the winter semester, the team is also in charge of organizing the annual BMS Student Conference, right after the BMS Days.
