It seems that the definition of an A∞category has to be extended in order to have wider applications.
We propose to extend it to the context of bimodules over V-categories. The ground category V is
assumed to be additive, closed symmetric monoidal, complete and cocomplete. We propose a
framework for enriched A∞-categories: we choose a V-category D, then we define an A∞-category
as a tensor D-bimodule equipped with the deconcatenation comultiplication and coderivation whose
square in a sense is 0.

I will give a survey on 3-manifolds and their triangulations (following Thurston),
and their combinatorics encoded in their NZ matrices. These were originally used
to compute hyperbolic volumes and Chern-Simons invariants, and more recently
have been used to define quantum invariants of 3-manifolds such as the 3D-index.

Parent event: 
Number theory lunch seminar

For zoom details contact Pieter Moree (moree@mpim-bonn.mpg.de).

In this talk, we aim to review some results about the sparsity of integral
points lying in orbits of rational maps in varieties over global fields,
and present about some of their consequences to multiplicative dependence
and arithmetic dynamics.

 

 

Open enumerative geometry for Landau-Ginzburg models and Mirror Symmetry

A Landau-Ginzburg (LG) model is a triplet of data $(X,W,G)$ consisting of a regular complex-valued function W from a quasi-projective variety X with a group G acting on X so that W is invariant. An enumerative theory developed by Fan, Jarvis and Ruan gives FJRW invariants, an analogue of Gromov-Witten invariants, for LG models. We define an open enumerative theory for certain LG models, building on the FJRW point of view. Roughly speaking, our theory involves computing specific integrals on certain moduli of discs with boundary and interior marked points.
