Xiangwen Zhang "A flow of conformally balanced metrics "
4:00 PM - 5:00 PM


Speaker: Xiangwen Zhang (Irvine) Abstract: We discuss the development on geometric and analytic as- pects of the Anomaly flow. While the flow was originally motivated by the study of Hull-Strominger system from string theory, its zero slope case is potentially of considerable interest in non-Kähler geometry, as it is a flow of (n−1, n−1) form with Kähler stationary points and preserves the conformally balanced property of the initial metric. We establish its long time existences and convergence on Kähler manifolds for suitable initial data by reducing it to a parabolic complex Monge-Ampère type equation which has no concave property. This is joint work with D. Phong and S. Picard.
Ilya Khayutin "Equidistribution of Special Points on Shimura Varieties. "
4:30 PM - 5:30 PM


Speaker: Ilya Khayutin (Princeton) Abstract: The André-Oort conjecture states that if a sequence of special points in a Shimura variety - Y - escapes all Hecke translates of proper Shimura subvarieties, viz. special subvarieties, then every irredicuble component of the Zariski closure of the sequence is an irreducible component of Y. A much stronger version of this conjecture is that the Galois orbits of a sequence of special points satisfying the assumption above equidistribute in connected components of Y. The latter conjecture would also imply the highly useful statement that the Galois orbits are dense in the analytic topology. Even more ambitiously, one would conjecture that orbits of large subgroups of the Galois group should equidistribute as well. The Pila-Zannier strategy which is the driving engine behind the spectacular recent progress on the André-Oort conjecture does not shed any light on these stronger questions of equidistribution and analytic density. The equidistribution conjecture is essentially known only for modular and Shimura curves following Duke's pioneering result in the 80's. I will discuss the relation of this problem to homogeneous dynamics and periodic torus orbits. I will then present two new theorems, for products of modular curves and for Kuga-Sato varieties, establishing partial results for the equidistribution conjecture by combining measure rigidity and a novel method to show that Galois/Torus orbits of special points do not concentrate on proper special subvarieties.
