Stability and wall-crossing
Tom Bridgeland
(Oxford)
Abstract:
In algebraic geometry and string theory there has been a lot of recent work on so-called wall-crossing phenomena for Donaldson-Thomas invariants.
In this talk we will study a baby example of wall-crossing, which already has some non-trivial consequences. I will not assume any previous knowledge of algebraic geometry, just some basic properties of the category of modules over a ring.
