Algebra and Geometry lecture series.

Time: Th 4-6, location: zoom (password was sent by Ivan on Aug 30).

Organized by Ivan Losev.

This seminar features lecture series by participants who are usually Yale faculty and postdocs.

Videos are posted in Yale box. In case they cannot access the Yale box, participants outside of Yale should contact Ivan.

The first lecture series is by Ivan and the topic is Quantizations in positive characteristic and applications. Click here for an abstract including a list of prerequisites and references.

  • Lecture 0: Prerequisite lecture about basics of quantizations. Includes the definition and examples of Poisson algebras, the definition and examples of filtered quantizations, the definition of formal quantizations and their relation with filtered ones. Finally, there is a discussion of quantizations of schemes.
