Datum: 
Mit, 18/10/2023 - 10:15 - Fre, 02/02/2024 - 12:00

The purpose of this course is to propose new foundations for analytic geometry. The topics covered are as follows:
1. Light condensed abelian groups.
2. Analytic rings.
3. Analytic stacks.
4. Examples.
Lectures will be given by Dustin Clausen at IHES and Peter Scholze at MPI, and broadcast live at the other location.
We also plan to make the lectures accessible by Zoom, and record them.

Abstract:

At the start of the 20th century, David Hilbert asked which representations can arise by studying the monodromy of Fuchsian equations. This question was the starting point for a beautiful circle of ideas relating the topology of a complex algebraic variety X to the study of algebraic differential equations. A central result is the celebrated Riemann-Hilbert correspondence of Kashiwara and Mebkhout, which supplies a fully faithful embedding from the category of perverse sheaves on $X$ to the category of algebraic $\mathfrak{D}_X$-modules. This embedding is transcendental in nature: that is, it depends essentially on the (archimedean) topology of the field of complex numbers. It is natural to ask if there is some counterpart of the Riemann-Hilbert correspondence over nonarchimedean fields, such as the field $\mathbf{Q}_p$ of $p$-adic rational numbers. In this series of lectures, I will survey some of what is known about this question and describe some recent progress, using tools from the theory of prismatic cohomology (joint work with Bhargav Bhatt).

Lecture course by Don Zagier on "Standard and less standard asymptotic methods"

Posted in
Speaker: 
Don Zagier
Datum: 
Die, 15/02/2022 - 16:00 - Mit, 23/03/2022 - 15:30

Starting February 15, Don Zagier will give a lecture course entitled "Standard and less standard asymptotic methods". This course will be given in collaboration with the IGAP (Institute of Geometry and Physics, a new joint venture between SISSA and ICTP in Trieste).

The course will be streamed from Trieste twice a week (Tu/Th 4-5:30 for the first four weeks and Mo/We 2-3:30 for the last two weeks).

Abstract:

In every branch of mathematics, one is sometimes confronted with the problem of evaluating an infinite sum numerically and trying to guess its exact value, or of recognizing the precise asymptotic law of  formation of a sequence of numbers ${A_n}$ of which one knows, for  instance, the first couple of hundred values.  The course will tell a number of ways to study both problems, some relatively standard (like the Euler-Maclaurin formula and its variants) and some much  less so, with lots of examples.   Here are three typical examples: 1. The slowly convergent sum  $\sum_{j=0}^\infty (\binom{j+4/3}{j})^{-4/3}$   arose in the work of a colleague.  Evaluate it to 250 decimal digits. 2.  Expand the infinite sum  $\sum_{n=0}^\infty (1-q)(1-q^2)...(1-q^n)$ as  $\sum A_n (1-q)^n$, with first coefficients 1, 1, 2, 5, 15, 53, ... Show numerically that  $A_n$  is asymptotic to  $n! * a * n^b * c$  for some real constants $a$, $b$ and $c$, evaluate all three to high precision, and recognize their exact values. 3.  The infinite series  $H(x) = \sum_{k=1}^\infty sin(x/k)/k$  converges for every complex number $x$.  Compute this series to high accuracy when $x$ is a large real number, so that the series is highly oscillatory.

The courses are scheduled as follows:

1 Tue 15-Feb 16.00 - 17-30
2 Thu 17-Feb 16.00 - 17-30

3 Tue 22-Feb 16.00 - 17-30

Modular fusion categories are mathematical structures appearing in mathematical physics (high energy and now condensed matter physics) and low dimensional topology (3d topological field theories).
The course will give an (elementary and example based) introduction to them and their very rough structure theory, governed by
the so-called Witt group of modular categories.

The course is meant to provide an informal and elementary introduction to
some of the notions of vertex operator algebras and conformal field theory,
to the modularity properties of the corresponding characters, and to the
“modular linear differential equations” satisfied by these modular forms

Mini-course: On the Hasse Principle for Divisibility in commutative algebraic groups

The Hasse Priciple is a fundamental topic in number theory. Anyway a complete proof is very seldom showed in undergraduate and graduate courses in number theory. We will decribe this classical result and prove it. After an overview of some long-established local-global principles, we will focus on the recent local-global question for divisibility in commutative algebraic group. In particular we will explain its relation with the Hasse principle for divisibility of elements of the Tate-Shavarevich group in the Weil-Châtelet group.  This latter problem arose as a generalization of a classical question considered by Cassels. We will describe the results achieved for the two problems during the last fifteen years and some questions that are still open.
