Introduction to D-modules


This lecture aims at giving a leisure introduction to the field
of algebraic analysis, that is, the algebraic study of linear partial
differential equations with polynomial coefficients. We will start
with basics on differential operators and the Weyl algebra as well
as on vector bundles with connections. We will discuss the notion
of holonomicity and how this gives finiteness restrictions on the solutions
of a D-module. Depending on time and audience, we will go into some details of
direct and inverse images, give the statement of the Riemann-Hilbert
correspondence, explain some facts about filtered D-modules as
well as on the V-filtration and Bernstein-Sato polynomials.

This lecture is to be continued in fall 2022.
