Title:Algebraic geometry through cut-and-paste

Abstract:

We will motivate and introduce the notion of Grothendieck ring of varieties in algebraic geometry, and explain how we obtain new results on Cremona groups through it in joint works with E. Shinder. (We assume zero background in algebraic geometry.)
