Title: Essential dimensions of polarized endomorphisms of abelian varieties
Abstract: We explore the essential dimension of polarized endomorphisms on abelian varieties and its relation with algebraic dynamics. This talk is based on joint work with Keiji Oguiso and De-Qi Zhang.

Title: Finiteness of heights in isogeny classes of motives
Abstract: Using integral p-adic Hodge theory, Kato and Koshikawa define a generalization of the Faltings height of an abelian variety to motives defined over a number field. Assuming the adelic Mumford-Tate conjecture, we prove a finiteness property for heights in the isogeny class of a motive, where the isogenous motives are not required to be defined over the same number field. This expands on a result of Kisin and Mocz for the Faltings height in isogeny classes of abelian varieties.
