## MPIM mourns death of Tobias Kreutz

The Max Planck Institute for Mathematics mourns the death of its postdoctoral fellow

**Tobias Kreutz** ( * 04.08.1996 - † 08.08.2024).

He completed his PhD in 2022 at the Humboldt University Berlin under the guidance of Bruno Klingler and Laurent Fargues. Since then he has been a visitor at the institute. Tobias has been working at the interface of complex and $p$-adic Hodge theory, with particular focus on the transcendental periods arising in both settings. In his last paper, he has proposed obstructions to complex Hodge structures being of geometric origin. He was a cherished member of our community and will be greatly missed by his friends and colleagues.

## Maryna Viazovska External Member of the Max Planck Institute for Mathematics

Maryna Viazovska, full professor and Chair of Number Theory at the Institute of Mathematics of the École Polytechnique Fédérale de Lausanne, has joined the Max Planck Institute for Mathematics as external scientific member. She was PhD student of Don Zagier from 2008-2012 and obtained her doctoral degree from the University of Bonn. Since then, she has returned to the institute regularly as a visitor and speaker. We are happy that Maryna will now play an even more active role in the research community and the development of the Max Planck Institute for Mathematics.

## Don Zagier Receives Fudan-Zhongzhi Science Award 2021

The Fudan-Zhongzhi Science Award 2021 is awarded jointly to Don Zagier and Benedict Gross for "their formulation and proof of the Gross-Zagier formula, which relates the height of Heegner points with the central derivatives of the zeta function of the corresponding elliptic curves. They established striking cases of the Birch and Swinnerton-Dyer Conjecture, which brought many applications to long-standing problems, and deeply influenced the development of number theory in recent decades." The prize committee also recognized Don Zagier's "profound work on modular forms and special functions which resolve questions and problems in diverse areas ranging from topology and moduli spaces to geometry and mathematical physics."

## Gaëtan Borot Awarded Dubrovin Medal of 2020

Gaëtan Borot, Advanced Researcher at the Max Planck Institute for Mathematics, is one of the first two recipients of the newly created Dubrovin Medal. The prize committee has recognized "his numerous and wide-ranging contributions to the theory of topological recursion leading to the proof of the Bouchard-Marino conjecture and to several applications to geometry and mathematical physics in the area of integrable systems."

## Arunima Ray appointed as Lise Meitner Group Leader

Arunima Ray, advanced researcher at the MPIM, was chosen as one of the 20 Lise Meitner Group Leaders from a field of 470 candidates. Launched in 2018 by the Max Planck Society, the Lise Meitner Excellence Program is aimed at women scientists who, even at the beginning of their scientific career, already rank among the exceptional talents in their area of research.

## Special online colloquium between IHES and MPIM

**Robert Penner** is a mathematician known for his works in geometry and combinatorics of moduli spaces, and holding the Rene Thom Chair in mathematical biology at IHES. In the past, he and coauthors have developed geometric tools to study RNA and protein folding. He recently became interested in viruses, notably to identify potentially interesting sites in glycoproteins present in the coronavirus responsible for the current epidemy. He will present this work during the talk, **Thursday 25th June 3-4.30pm** local time.

## Maryna Viazovska Awarded 2017 Ramanujan Prize

Maryna Viazovska, who conducted her doctoral research at the Max Planck Institute for Mathematics from 2008-2012 under the guidance of Don Zagier, was awarded the Ramanujan Prize for 2017. Professor Viazovska is honored “for her stunning solution in dimension 8 of the celebrated sphere packing problem, and for her equally impressive joint work with Henry Cohn, Abhinav Kumar, Stephen D. Miller and Danylo Radchenko resolving the sphere packing problem in dimension 24, by building upon her fundamental ideas in dimension 8.” The prize also recognizes her outstanding PhD thesis of 2013 at the University of Bonn in which she resolved significant cases of the Gross-Zagier Conjecture and her work prior to her PhD with A. Bodarenko and D. Radchenko resolving a long-standing conjecture of Korevaar and Meyers on spherical designs, that appeared in the Annals of Mathematics in 2013. The prize notes that the modular forms techniques developed by Viazovska will have a significant future impact in discrete geometry, analytic number theory, and harmonic analysis. It was awarded on December 22 (Ramanujan's birthday), 2017 at the International Conference on Number Theory at SASTRA University in Kumbakonam, India, Ramanujan’s hometown.

## Exhibition "Women of Mathematics throughout Europe" at MPIM opening on November 10th

The exhibition "Women of Mathematics throughout Europe" will be on public display at the Max Planck Institute for Mathematics from November 10 to December 23, 2016. This touring exhibition, whose starting point is the 7th European Congress of Mathematics held in July 2016 in Berlin, features the portrays of thirteen female mathematicians, sharing their experience, thus serving as role models to encourage young women to enter mathematics, a field where women are still largely underrepresented. The exhibition will be launched with the:
