Title: Measurements of varieties

Date: Oct 20, 2015, 17:30-19:00

Place: Eckhart 312, U Chicago

I will discuss a few ways how to define various rings of varieties and rings of categories, and how to introduce algebraic operations on these rings. These rings can be thought as decategorifications of the respective categories, and some of them possess natural algebraic operations which can be recategorified. It is possible to prove identities in these rings, which might be powerful enough to answer geometric questions. Talk is based on joint works with Evgeny Shinder.
