## 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.

## Max Planck Institute for Mathematics in Bonn Mourns Death of Yuri Manin

**Emeritus director of institute passed away at age 85**

*Bonn, January 8, 2023.* The Max Planck Institute for Mathematics in Bonn mourns the death of Professor Yuri Ivanovich Manin. The eminent mathematician passed away on Saturday, January 7, at the age of 85. Yuri Manin was a scientific member and director of the Max Planck Institute for Mathematics from 1992 to 2005, after which he remained an extremely active emeritus director. His work largely influenced the development of modern mathematics. With Yuri Manin, mathematics has lost one of his truly great personalities. He was a wonderful human being and a renowned researcher whose contributions have shaped the entire field. Our institute will always remain his institute, too.

## Ana Caraiani Awarded Max Planck Fellowship

Ana Caraiani, who holds the Hausdorff Chair at the University of Bonn, is newly appointed Max Planck Fellow at the Max Planck Institute for Mathematics. The Max Planck Fellowship is a prestigeous honor bestowed on outstanding university professors by the Max Planck Society for a limited term of 5 years. The fellows receive funds to build up a small research group at the host institute. The goal is to promote cooperation between university faculty and Max Planck Society researchers.

## Pius XI Medal Awarded to Peter Scholze

Peter Scholze, director at the Max Planck Institute for Mathematics and professor at the University of Bonn, was awarded the Pius XI Gold Medal 2020 by the Pontifical Academy of Sciences. The medal is awarded every two years to a young scientist under the age of 45, chosen for his or her exceptional promise. After Luis A. Caffarelli (1988), Laure Saint-Raymond (2004), and Cédric Villani (2014), Peter Scholze is only the fourth mathematician to receive this honor.

## Fields Medal awarded to Maryna Viazovska. Former doctoral student of the Max Planck Institute for Mathematics receives highest distinction in mathematics

**The Fields Medal is considered the Nobel Prize of mathematics. This year the International Mathematical Union chose to award it to Maryna Viazovska, who wrote her doctoral thesis at the Max Planck Institute for Mathematics with Don Zagier and received her PhD from the University of Bonn in 2013. The Ukranian mathematician is second woman to ever receive this prize.**

## Peter Scholze Elected Foreign Member of the Royal Society

Peter Scholze, director at the Max Planck Institute for Mathematics and professor at the University of Bonn, was elected Foreign Member of the Royal Society.

## ERC Starting Grant for Tobias Barthel

Tobias Barthel, advanced researcher at the Max Planck Institute for Mathematics, has received a prestigeous ERC starting grant for his project on the "spectral geometry of higher categories". The total budget of the grant is 1.5 million euros for the project duration of 5 years. The eleven Max Planck grantees are among the 397 young researchers who received an ERC Starting Grant in 2021.

The European Research Council (ERC) is the premier European funding organisation for excellent frontier research. It funds creative researchers of any nationality and age, to run projects based across Europe. The ERC offers four core grant schemes: Starting Grants, Consolidator Grants, Advanced Grants and Synergy Grants. The ERC is led by an independent governing body, the Scientific Council. Its prestigeous grants are awarded anually.

## 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."

## Dennis Gaitsgory New Director at MPIM

Dennis Gaitsgory is a newly appointed director at the Max Planck Institute for Mathematics in Bonn. He will join the three active directors Gerd Faltings, Peter Teichner, and Peter Scholze in July 2021.

**Dennis Gaitsgory** was Born in 1973 in Moldava, a republic of the Soviet Union at the time. He studied at Tel Aviv University under Joseph Bernstein from 1990–1996, where he received his doctorate in 1997 for a thesis on "Automorphic Sheaves and Eisenstein Series". In the academic years 1996/97 and 1998/99 he was at the Institute for Advanced Study in Princeton. In 2001 he became Associate Professor at the University of Chicago before joining the faculty of Harvard University in 2005.

## Danica Kosanović Receives Hausdorff Memorial Prize

Danica Kosanović is one of the two prize winners of the Hausdorff Memorial Prize for the best PhD thesis in mathematics at the University of Bonn in 2019/2020. In her thesis on “A geometric approach to the embedding calculus knot invariants”, which was supervised by Peter Teichner, she proved a 30 year old conjecture about invariants of classical knots.
