Recent developments in Quantum Topology -- Cancelled --

Posted in

We will review the basics of quantum topology such as the colored Jones polynomial of a knot, its standard conjectures relating to asymptotics, arithmeticity and modularity, as well as the recent quantum hyperbolic invariants of Kashaev et al, their state-integrals and their structural properties. The course is aimed to be accessible by graduate students and young researchers.

Algebraic spaces and Algebraic stacks

Praphulla Koushik
Affiliation: 
School of Mathematics, IISER Thiruvananthapuram, India
Date: 
Mon, 2020-08-10 10:30 - 12:00
Parent event: 
Online reading group "Intersection theory on stacks"

In this talk, after recalling the notion of a stack over an arbitrary site, I will introduce the notions of an algebraic space, an algebraic stack and a Deligne-Mumford stack. I will then introduce some examples and properties of these "generalized schemes".

Online: Noncommutative Weil conjectures

The Weil conjectures (proved by Deligne in the 70's) played a key role in the development of modern algebraic geometry. In this talk, making use of some recent topological "technology", I will extended the Weil conjectures from the realm of algebraic geometry to the broad noncommutative setting of differential graded categories. Moreover, I will prove the noncommutative Weil conjectures in some interesting cases.

Finite descent and the Lawrence--Venkatesh method

Posted in
Speaker: 
Alexander Betts
Affiliation: 
King's College London/MPIM
Date: 
Wed, 2020-08-26 14:30 - 15:30
Parent event: 
Number theory lunch seminar

If Y is a curve of genus at least 2 over a number field, then the finite descent obstruction cuts out a subset of the adelic points, which is
conjecturally equal to the set of rational points. In particular, we expect this set to be finite. In this talk, I will present ongoing work with Jakob
Stix proving that certain projections of the finite descent locus are finite, as predicted by this conjecture. The method we employ can be
loosely described as "Lawrence--Venkatesh for Grothendieck's section set".

Definition and examples of stacks

MPIM
Date: 
Mon, 2020-08-03 10:30 - 12:00
Parent event: 
Online reading group "Intersection theory on stacks"

As motivation, we will start by considering the category of continuous functions and illustrate some gluing properties that make it a stack over the category of topological spaces. We will then give the definition of a stack and explore some other examples of stacks coming from algebraic geometry.

Online: L-series values of twists of elliptic curves

Parent event: 
Number theory lunch seminar

We consider certain families of sextic twists of the elliptic curve y^2=x^3+1 that are not defined over Q, but over Q[sqrt(-3)]. We compute a formula that relates the value of the L-function L(E_D, 1) to the square of a trace of a modular function at a CM point. Assuming the Birch and Swinnerton-Dyer conjecture, when the value above is non-zero, we recover the order of the Tate-Shafarevich group and show that its value is a square.
