报告内容：Recently, the Ax-Schanuel conjecture for Shimura varieties has been resolved in Mok-Pila-Tsimerman [3]. In this mini-course, we discuss the strategy in [3]. Special focuses will be placed on the complex differential and algebraic techniques involved in some of the main steps of the proof. We will also discuss some related problems and results from complex analytic perspective.

Content 1. Functional transcendence. Classical transcendence theory in number theory is one of the most important motivation of modern functional transcendence theory. We recall some classical results and relate them to the function field analogue of the transcendence theory. The relationship with Hodge theory and atypical intersections will also be considered.

2.Hermitian symmetric spaces. Shimura varieties are arithmetic quotients of bounded symmetric domains. We introduce bounded symmetric domains first from the point of view of several complex variables. Then we indicate how these domains serve as bounded domain realization of Hermitian symmetric spaces of noncompact type, together with a brief review of the important properties.

3. Volume estimates on Shimura varieties. One of the key ingredients for the proof of Ax-Schanuel for Shimura varieties is the volume estimates of Hwang-To [1]. We discuss some differential geometric aspects of bounded symmetric domains and their finite volume quotients, which give necessary preparations for the proof of Hwang-To’s estimates.
