DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGSeminar/1/
 ">Examples of four-dimensional geometric transition</a>\nby Andrea Seppi (
 Université de Grenoble) as part of Sapienza A&G Seminar\n\n\nAbstract\nRo
 ughly speaking\, a geometric transition is a deformation of geometric stru
 ctures on a manifold\, by “transitioning” between different geometries
 . Danciger introduced a new such transition\, which enables to deform from
  hyperbolic structures to Anti-de Sitter structure\, going through another
  type of real projective structures called “half-pipe”\, and provided 
 conditions for a compact 3-manifold to admit a geometric transition of thi
 s type. By extending a construction of Kerckhoff and Storm\, I will descri
 be examples of finite-volume geometric transition in dimension 4.\n\nThis 
 is joint work with Stefano Riolo.\n
