Diophantine problems and a p-adic period map

Brian Lawrence (University of Chicago)

Abstract: I will outline a proof of Mordell's conjecture / Faltings's theorem using p-adic Hodge theory. I'll start with a discussion of cohomology theories in algebraic geometry, and build from there. The paper is joint with Akshay Venkatesh.

Atoroidal dynamics of subgroups of \(Out(F_N)\)

Caglar Uyanik (Yale)

Abstract: I will discuss several examples to illustrate how the dynamics of the \(Out(F_N)\) action on various spaces reflects on the algebraic structure of the \(Out(F_N)\) itself. In particular, I will talk about a new subgroup classification theorem for \(Out(F_N)\) which is joint work with Matt Clay.

New examples of Calabi-Yau metrics on a complex vector space

Frederic Rochon (University of Quebec in Montreal)

Abstract: After reviewing how the Riemann curvature tensor describes the local geometry of a space and how it may reflect some global aspects of its topology, we will focus on a special type of geometry: Calabi-Yau manifolds. By smoothing singular Calabi-Yau cones and using suitable compactifications by manifolds with corners, we will explain how to construct new examples of complete Calabi-Yau metrics on a complex vector space. Our examples are of Euclidean volume growth, but with tangent cone at infinity having a singular cross-section. This is a joint work with Ronan J. Conlon.
