Typical and Atypical Intersections: Geometry, Dynamics, and Applications - Gregorio Baldi

Special Year Research Seminar 1:00pm|Simonyi 101 Topic: Typical and Atypical Intersections: Geometry, Dynamics, and Applications Speaker: Gregorio Baldi Affiliation: Institute for Advanced Study Date: December 11, 2025 Many geometric spaces carry natural collections of special submanifolds that encode their internal symmetries. Examples include abelian varieties and their sub-abelian varieties, locally symmetric spaces with their totally geodesic subspaces, period domains with their sub–period domains, and strata of abelian differentials with their affine invariant submanifolds. In recent years, major progress has been made in understanding these structures through the framework of unlikely intersections and functional transcendence. In the first lecture, I will survey how this perspective can be applied to the study of non-arithmetic complex hyperbolic lattices and affine invariant submanifolds, complementing existing dynamical approaches. In the second lecture, I will outline the proof of the geometric Zilber–Pink conjecture and discuss general results on the distribution of the Hodge locus.
