New BMS Student RepresentativesEach 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: Aizhan Issagali, Coco Bögel, Dante Luber, Lenny Leass, Margarita Kostré, and Marwa Zainelabdeen. The new team will start their term in December, while the recent BMS student representatives  Andrei, Paramjit, Sandro, Sofía, Tatiana, and Vira  will still be responsible for the Career Day on 10 December 2021 and for the student conference in 2022. 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 organize an annual survey of BMS students. To help BMS students get to know each other and provide opportunities for networking, they offer a wide range of activities like

Application deadline: 1 December 2021 (23:59:59, Berlin time, UTC +1 hour) Honoring Jürg KramerMATH+ takes this opportunity to wish Jürg Kramer all the best for a happy 65^{th} birthday! His outstanding commitment to Berlin mathematics and to young mathematicians within MATHEON, the Berlin Mathematical School (BMS), DZLM and MATH+ make him one of our most highly valued members. Born in Switzerland on 3 June 1956, he started his mathematical career at the University of Basel, where he got his diploma in mathematics with minors in physics and astronomy in 1980 and received his doctorate under Martin Eichler in 1985. Postdoc positions took him to the Max Planck Institute for Mathematics in Bonn, to Harvard University, the MSRI, Universität Wuppertal, and to ETH Zurich, where he completed his habilitation in 1993. In 1994, he accepted the offer of a professorship at HumboldtUniversität zu Berlin (HU Berlin). After his arrival in Berlin, Jürg Kramer soon took on essential leadership roles. He was deputy director and director of the Institute of Mathematics at HU Berlin from 1998 to 2008. A member of the DFG Research Center Matheon since its founding in 2002, he served on the MATHEON Executive Board from 2007 to 2014. He was also one of the founding fathers of the Berlin Mathematical School (BMS) and has served as chair or cochair since 2006. In 2013, he was one of the initiators of the Einstein Center for Mathematics ECMath, where he also served on the Executive Board. From 2013 to 2014, Jürg Kramer served as President of the German Mathematical Society (DMV). He is a member of the European Mathematical Society, the Academia Europea, Acatech, and INNOMATH – a European initiative to support highly gifted high school students. Throughout his career, Jürg Kramer has been devoted not only to mathematics itself but also to the education and training of mathematics teachers and the advancement of mathematically talented and interested school pupils, students, and teachers – from elementary schools to doctoral researchers. Moreover, his research group aims to make current mathematical developments accessible to the public at large. This commitment is expressed in his engagement in the Berlin network of STEM schools at HU Berlin (Berliner Netzwerk mathematisch naturwissenschaftlicher Schulen) as well as his support for the “Mathematical Kangaroo” (Känguru der Mathematik), the largest international mathematics competition for school children, which is based at the Institute of Mathematics at HumboldtUniversität zu Berlin. In 2010, a group of experts convened by the Deutsche Telekom Foundation (DTS) proposed a national advanced training center for mathematics as an important building block in its recommendations on Mathematik entlang der Bildungskette (“Mathematics along the educational chain”). As a result, the DTS issued a call for applications providing funding for five years to establish such a center. Based on his project Mathematik anders machen (“Doing Mathematics Differently”) Jürg Kramer organized a consortium of universities, which submitted the winning proposal. Thus, the Deutsches Zentrum für Lehrerbildung Mathematik (DZLM) was founded in October 2011. Jürg Kramer has been the Director of DZLM since the beginning and saw the DZLM find a permanent home as part of a new department Fachbezogener Erkenntnistransfer (“SubjectSpecific Transfer of Knowledge”) of the Leibniz Institute for Science and Mathematics Education (IPN) Kiel in 2020. He is now director of the department. The success story of DZLM would have been impossible without Jürg Kramer’s experience in large collaborative projects like MATHEON, BMS, ECMath, and MATH+, his strong commitment, his excellent networking and communication skills and not least at all his personality and respectful attitude to other people. In addition to his numerous engagements, Jürg Kramer is also an outstanding researcher, with interests in number theory, automorphic forms, and arithmetic geometry. He chaired two DFG Research Training Groups Arithmetic and Geometry (20042009) and Moduli and Automorphic Forms (20122016). Anna von Pippich elaborates on Jürg Kramer’s research. Last but not least, Jürg Kramer is a key member of the Berlin Mathematics Research Center MATH+ and contributed an important part to the successful application for MATH+ in the framework of the German Excellence Strategy. With all his energy and commitments, Jürg Kramer has significantly contributed to the shape of the mathematical landscape in Berlin and has helped to make it an internationally attractive destination for study and research. Due to his efforts, there are many mathematicians around the world who owe their education to Berlin mathematics! Dear Jürg, MATH+ wishes you a happy birthday and we look forward to working together on many more activities!

ERC Advanced Grant for BMS Faculty Member Bruno KlinglerOn 22 April 2021, the European Research Council (ERC) announced which innovative research projects will be funded by the ERC Advanced Grant for established researchers. Out of 2678 proposals from across Europe and all scientific disciplines, only 209 projects (8%) were approved; these projects will be funded with in total 507 million euro over a fiveyear period. The project “Tame geometry and transcendence in Hodge theory” (TameHodge) by Bruno Klingler will be funded by the ERC with more than 1.8 million euro. The project plans to attack fundamental questions in Hodge theory using tools coming from mathematical logic. Hodge theory, as developed around the 1970s, has become the main tool for understanding the geometry and arithmetic of complex algebraic varieties, that is, solution sets of algebraic equations over the complex numbers. It can be thought as a dramatic linearisation, which associates to any complex algebraic variety a very simple object: a finite dimensional complex vector space, which encodes the periods of differential forms on the variety. At the heart of the theory lies the fundamental fact that, although Hodge’s theory produces very simple objects, it is not itself given by a simple algebraic recipe but requires transcendental operations. However, two major conjectures in mathematics, the Hodge conjecture and the Grothendieck period conjecture, predict that this transcendence is severely constrained. Recent work of Prof. Klingler and his collaborators has shown the emergence of a spectacular link between Hodge theory and tame geometry. Tame geometry, whose possibility was suggested by Grothendieck in the 1980s and developed by logicians under the name ominimal geometry, studies structures where every definable set has a finite geometric complexity. The goal of the project TameHodge is to show that moderate geometry is the natural framework for Hodge theory—with major applications to the transcendence of periods, atypical intersections, and nonabelian Hodge theory. Since 2017, Bruno Klingler is professor for Algebraic Geometry at HumboldtUniversität zu Berlin; as such he is one of 20 Einstein professors. Furthermore, Prof. Klingler is a MATH+ member and a faculty member of the Berlin Mathematical School. Before moving to Berlin, Bruno Klingler was a full professor at the Institut de Mathématiques de JussieuParis Rive Gauche (IMJPRG), Université Paris, as well as assistant professor at University of Chicago and Yale University.

The prizegiving ceremony was held at TU Berlin on 19 December 2019. Many congratulations to Mark! Fruitful Second BMS – BGSMath Junior Meeting in BerlinThe second Junior Meeting of the BMS and the Barcelona Graduate School of Mathematics (BGSMath) took place in Berlin from 26 to 28 June 2019. In total, 17 participants from Barcelona and 25 from Berlin joined the event. The Junior Meetings were launched with a first meeting in Barcelona in October 2017 to create strong scientific exchange, strengthen research collaboration between the respective math communities, and enhance the multicultural environment of both graduate schools. The second Junior Meeting now aimed to intensify current collaborations and create new links between the two schools. In their opening remarks, BMS Deputy Chair Prof. Dr. Jürg Kramer and BGSMath Director Prof. Dr. Marta SanzSolé restated their common goal of striving for excellence in their doctoral and postdoctoral training programs. They also emphasized the importance of networking and of creating diverse frameworks for lively exchange. The threeday scientific program provided a wealth of interesting halfhour talks by 18 doctoral students and postdocs from the two schools. Mario Kummer (TU Berlin), Albert MasBlesa (Universitat Politècnica de Catalunya), and Thomas Krämer (HU Berlin) gave onehour talks as plenary speakers. The thematic focus was on three main areas: “With so many areas of mathematics represented, the participants were able to learn about what their colleagues outside of their own research areas are working on and to see connections between different fields”, summarized Tal Orenshtein and Andrew Newman from the organizing committee. “The coffee breaks, the Welcome Reception in the BMS Lounge, and the Conference Dinner made lively exchange and discussions about maths and beyond possible.” The meeting was organized by a committee of postdocs from the two institutes: Joan Bosa and Marina Gonchenko (both from BGSMath), JeanPhilippe Labbé, Andrew Newman, and Tal Orenshtein (all from the BMS), and chaired by Prof. Kramer and Prof. SanzSolé. In 2016, a memorandum of understanding was signed by both graduate schools in order to boost collaborative work between young researchers from both institutions. The schools declared their intention to cooperate together in initiatives aimed at promoting the mobility of and exchange between students and faculty members by way of events such as the Junior Meeting; joint summer schools; mutual visits by advanced students and postdocs of each institution; and other scientific activities.
