Flexible varieties, images of affine spaces, and ellipticity after Mikhail Gromov

Abstract We define flexible affine algebraic varieties, describe their basic properties, and show that many varieties satisfy the flexibility condition. The group of special automorphisms acts in

General behavior ofarea-minimizing subvarieties

Abstract We will review some recent progress on the general geometric behavior of homologically area-minimizing subvarieties, namely, objects that minimize area with respect to homologous

Applications of o-minimality to Hodge theory IV | Algebraic and Complex Geometry Seminar

Abstract The goal of this minicourse is to introduce the recent advances in Hodge theory via o-minimal techniques. We will start by revisiting the basics on o-minimal geometry with a view towards
