"Hot Topics" Conference on "Quantum Topology", May 12 - 16, 2025

The discovery of polynomial invariants of knots by Jones sparked the study of quantum topology in the late 80s and 90s. Work over the last two decades has led to deeper understanding of the mathematical structures behind these invariants.

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.

For the purpose of today, an "I-Type Knot Invariant" is a knot invariant computed from a knot diagram by integrating the exponential of a pertubed Gaussian Lagrangian which is a sum over the features of that diagram (crossings, edges, faces) of locally defined quantities, over a product of finite dimensional spaces associated to those same features.

Q. Are there any such things?
A. Yes.

Q. Are they any good?
A. They are the strongest we know per CPU cycle, and are excellent in other ways too.

In the last years many interesting connections have been found between quantum invariants of links and three-manifolds, and topological strings on Calabi-Yau threefolds. In this talk I will focus on state integral invariants of hyperbolic knots, their perturbative expansion, and the resurgent structure of the latter.

The $sl_n$-skein algebra of a surface provides a quantization of the $SL_n(\mathbb{C})$ character variety. For surfaces with boundary, this framework extends naturally to the stated skein algebra. We demonstrate how various aspects of quantum groups admit simple and transparent geometric interpretations through the lens of stated skein algebras. In particular, we will present a geometric realization of the dual canonical basis of $\mathcal{O}_q(\mathfrak{sl}_3)$ using skeins.

Braided Hopf structures on exterior algebras

I will explain how the theory of Nichols algebras allows one to endow the exterior algebra of a vector space of dimension greater than one with a one-parameter family of braided Hopf algebra structures. The structure constants with respect to a natural set-theoretic basis can be explicitly computed, although determining the braiding structure in explicit terms is rather challenging. There exists a one-parameter family of diagonal automorphisms, which make it possible to construct solutions to the (constant) Yang--Baxter equation.

The $SL_2(C)$-skein modules of closed 3-manifolds were defined by in the 90’s but till recently little was known about their structure. The modules depend on a parameter A and can be considered over $ {\mathbb Z}[A^{\pm 1}]$ or over ${\mathbb Q}(A)$.

The ${\mathbb Q}(A)$-module is known to be finitely generated  while the structure over ${\mathbb Z}[A^{\pm 1}]$ can be complicated.

A handout for this talk will be available at https://www.rolandvdv.nl/Talks/Stavros25/.
In joint work with Daniel Lopez Neumann we showed how the quantum invariants arising from the twisted double yield a lower bound for the knot genus. We will give an elementary sketch of the construction and discuss further applications.

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.

In 1978, Apery proved that zeta(3) was irrational. Perhaps unexpectedly, his methods have
proven exceptionally hard to generalize. In recent work with Dimitrov and Tang, we have found a new framework with which to study these ideas, with a number of applications both to modular forms and irrationality. Our aim will be to give a gentle overview of our ideas, as well as highlight a number of basic open questions about G-functions which Riemann would understand.

In joint work with Garoufalidis–Scholze–Zagier, we constructed elements in generalized Habiro rings associated to number fields. A central aspect of this work involved lifting analytic to algebraic data—a process that can be viewed as a form of analytic continuation. In ongoing work with Garoufalidis, we extend these techniques to the setting of hypergeometric motives, replacing algebraic functions with periods. When interpreted appropriately, this yields power series expansions around roots of unity whose coefficients are explicitly computable cohomology classes.
