Conference on "Progress and Emergent Theories in Zeta and L-Functions" (PRETZL), July 21-25, 2025

There has been an enormous amount of progress in the analytic theory of zeta and L-functions over the past decade. Our understanding in the classical theory of the value distribution of the Riemann zeta function has achieved new heights with spectacular breakthroughs on moments and extreme values (both local and global) leading to a better understanding of families of L-functions more generally.

Conference in Memory of Yuri Manin, August 11 - 15, 2025

Yuri I. Manin (February 16, 1937 - January 7, 2023) was an extraordinary figure in mathematics. Renowned for his creativity, Professor Manin's profound insights -- in diverse subjects ranging from algebraic geometry to mathematical physics and quantum computing -- helped shape modern mathematics. Professor Manin was Director of the Max Planck Institute for Mathematics in Bonn. In this week-long conference, the institute will honor his results and ideas and will attempt to trace some of their developments.

Cohomology of ($\phi$, $\Gamma$)-modules was studied by Herr, Liu, and Kedlaya-Pottharst-Xiao. Kedlaya-Pottharst-Xiao proved finiteness, duality, and Euler-characteristic formula for cohomology of families of ($\phi$, $\Gamma$)-modules.

Higher differentials in the cohomology spectral sequence for long knots

Parent event: 
MPIM Topology Seminar

There are two cohomology spectral sequences computing invariants of families of long knots in R^3, due respectively to Goodwillie-Sinha and Vassiliev, that conjecturally agree. Rationally it is known that they both collapse at the second page. Vassiliev conjectured that this is the case over all coefficients. In order to perform explicit computations we define a small multicomplex based on the Fox Neuwirth decomposition of configuration spaces, that produces higher differentials in the Goodwillie-Sinha spectral sequence.

Coefficients of modular forms modulo (powers of) primes

Parent event: 
PLeaSANT (Participative Learning Seminar on Any Number Theory)

In this talk, we will try to discuss some properties of the coefficients of classical modular forms modulo primes or prime powers. The talk will be divided into two parts. The first part will be concerned with holomorphic modular forms, particularly weight 2 newforms, and discuss partly on a joint work with Tian Wang on their ordinary primes. The second part will be concerned with meromorphic modular forms (of level 1), and discuss some numerical congruences satisfied by their coefficients.

Approximation of perfectoid rings by Noetherian rings and prisms

MPIM Seminar Room
Parent event: 
Algebra Seminar

The theory of perfectoid towers, introduced by Ishiro-Nakazato-Shimomoto, provides an axiomatic approach to perfectoid theory in commutative algebra through tower-theoretic approximations. In contrast, Bhatt and Scholze introduced prisms as a "deperfection" of perfectoid rings. Our main result shows that a "gradual perfection" of a prism becomes a perfectoid tower. As a consequence, we prove that any p-torsion-free p-adically complete delta-ring that is reduced modulo p admits a perfectoid tower.
