Abstract:
The Chow ring of a variety encodes a lot of information about its geometry and is the subject of many interesting conjectures. A conjecture of Shen-Vial predicts that the Chow ring of any hyperkaehler variety admits a multiplicative Chow-Kunneth decomposition. I will begin by recalling some of the basic properties of the Chow ring, the origins of the conjecture and then discuss some of the known cases. I will discuss in detail the case of Hilbert schemes of points on a K3 surface. This is joint work in progress with R. Laterveer.
