Derived algebraic geometry is an ‘update’ of algebraic geometry using ‘derived’ (roughly speaking, homological) techniques. This requires recasting the very foundations of the field: rings have to be replaced by differential graded algebras (or other forms of derived rings), categories by higher categories, and so on. The result is a powerful set of new tools, useful both within algebraic geometry and in related areas. The school serves as an introduction to these techniques, focusing on their applications.

The school is built around two related courses on geometric (‘derived spaces’) and categorical (‘derived categories’) aspects of the theory. Our goal is to explain the key ideas and concepts, while trying to keep technicalities to a minimum.

School Structure

Two lectures will be held in the mornings. The afternoons will consist of problem sessions in which students will be given exercises directly related to the course subject. There will also be discussion sessions where interaction will be more free form and would cover higher-level topics, making the material exciting for advanced students while also provided less advanced students with a broader view of the field.

Suggested Prerequisites

Suggested Readings

  • D. Gaitsgory. Generalities on DG categories The notes (only 17 pages!) summarize properties of dg categories for future applications
  • V. Drinfeld. DG quotients of DG categories This (essentially self-contained) paper focuses on quotients and localization (which, in particular, is necessary to define derived categories). Section 1 is recommended reading in preparation for the school; the rest of the paper may be best left until after the school.
