Counting sheaves on K3 surfaces in 3 folds and 4 folds

Abstract We discuss the enumerative geometry of moduli spaces of sheaves with 2 dimensional support on K3 surfaces in K3-fibered threefolds and 4 folds. The reason to study such specific geometric

An irregular Deligne-Simpson problem and Cherednik algebras

Abstract The Deligne-Simpson problem asks for a criterion of the existence of connections on an algebraic curve with prescribed singularities at punctures. We give a solution to a generalization

Symmetry group of PDE and application in numerics (part I)

Abstract In this talk, we will focus on symmetry of PDE and report some relation with deep learning. It is a well known fact that Lie group is a fundamental tool to describe the symmetry. In

Calabi-Yau 3-folds in projective spaces and Gorenstein rings

Abstract The defining ideal $I_X$ of a projectively normal Calabi-Yau 3-fold $X$ is arithmetically Gorenstein, of Castelnuovo-Mumford regularity 4. Such ideals have been intensively studied when $I...

Integrability in 2D statistical systems and in 1+1 dimensional quantum field theory

Introduction The goal of these lectures is to introduce the roots and developments of the Integrability until modern applications in 1+1-d quantum field theories and 2d statistical mechanics.
