讲座主题：Transfer principles for Galois cohomology and Serre's conjecture II
讲座摘要: In this talk, I will present some transfer principles for the cohomological dimension of fields. I will then show some applications to Serre's Conjecture II, which predicts a characterization of cohomological dimension 2 fields in terms of rational points on torsors under algebraic groups. In particular, we will see that Serre's Conjecture II for characteristic zero fields implies the same conjecture for positive characteristic fields. This is joint work with Giancarlo Lucchini Arteche.
