摘要 Abstracts

Haoyu Hu: Introduction to D-modules
The series of lectures is divided into two parts. In the first part, we discuss the fundamental notions of algebraic D-modules theory, including six functors and characteristic varieties. In the second part, we focus on the Riemann-Hilbert correspondence for regular meromorphic connections.

Laurentiu Maxim: Singularities via mixed Hodge modules
I will start by giving a brief introduction to the theory of mixed Hodge modules. I will then proceed to show how this theory can be used to investigate singularities of complex algebraic varieties, especially of hypersurfaces.

Yichen Qin: Mixed Hodge modules
The aim of this lecture series is to introduce Morihiko Saito's theory of mixed Hodge modules. We will first recall some background on variations of mixed Hodge structures, D-modules, and perverse sheaves. We will then define the category of mixed Hodge modules and discuss some important results, such as the decomposition theorem and stability under the 6-functor formalism.

Daxin Xu : Introduction to arithmetic D-modules
The rigid cohomology is a Weil cohomology for varieties over field of positive characteristic. The theory of arithmetic D-module is the 6-functor formalism for the rigid cohomology. This theory is built on the works of Berthelot, Caro, Abe and others. In this course, I will explain some constructions and results in this theory.
