Title: G-stable rank for tensors and its applications

Abstract: G-stable rank is a new notion of rank for tensors over perfect fields, it is closely related to the stability in geometric invariant theory. We will talk about the motivation of G-stable rank and some of it's properties. We will also discuss the connection to stability. Finally, as an example, we will look at the application of G-stable rank to Cap Set problem.
