Introduction to derived algebraic geometry

Summer 2025, Regensburg

Contents

We introduce the basic concepts in derived algebraic geometry—such as animated rings, derived schemes, derived algebraic stacks, and quasi-coherent modules—and discuss their basic properties. This course aims to discuss an algebraicity result of Weil restrictions.

When and where

Fridays from 10:15 till 11:45 in M101. The first meeting is 25th of April. 

You can also attend on Zoom via this link.  The passcode is 307612.

Addendum

1. During lecture 2 in the definition of a filtered category C I should have said that the poset A is supposed to be finite (corrected in the notes).
