Title: Algebraic K-theory of singular hypersurfaces

Abstract

Considering short exact sequences of enhanced triangulated categories naturally leads to the notion of algebraic K-theory. Although recent years have seen substantial progress in the area, there are still few complete computations of (higher) K-theory of singular varieties: in positive characteristic there are essentially none in dimension >1 in the literature, and the situation in characteristic 0 is not much better. In this talk, I will show how recent developments in algebraic K-theory can be used to understand the K-theory of singular varieties, focusing on cubic surfaces and threefolds, where complete computations can be obtained in many cases.
