## "The Quadratic Formula Revisited". Hirzebruch lecture by Bernd Sturmfels on Thursday, 9 November 2023, University Club Bonn

High school students learn how to express the solution of a quadratic equation in one unknown in terms of its three coefficients. Why does this formula matter? We offer an answer in terms of discriminants and data. This lecture invites the audience to a journey towards non-linear algebra.

## 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.

## "Moduli in Mathematics". Hirzebruch lecture by Rahul Pandharipande on Monday, 15 May 2023, University Club Bonn

**Moduli** spaces parameterize continuous deformations of mathematical objects. Their study (starting with ideas of Riemann in the 19th century) has revealed many surprises: universal structures, connections between different subjects, and wild leaps. I will present some sense of the motivations and results related to the study of moduli spaces from the perspective of examples ranging from configurations of mechanical linkages to the moduli of varieties and sheaves.

## 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.

## Memorial Event for Yu. I. Manin

The Max Planck Institute will hold a memorial event for Yuri Ivanovich Manin this Friday, January 13, from 16:00 - 17:30h in the lecture hall. The mathematical community and friends are welcome to attend in person or online:
