Ruprecht-Karls-Universität Heidelberg Mathematisches Institut Prof. Dr. Anna Wienhard Prof. Dr. Peter Albers Heidelberg, 28.06.2019 Differential Geometry Seminar "Families of Geometries and Transitions" Steve Trettel, University of California, Santa Barbara, USA Abstract: A geometric transition is a continuous path of geometries/geometric structures which changes in isomorphism type, generalizing the transition from hyperbolic to Euclidean geometry as curvature goes to zero. In this talk I will give an overview of a new formalism for discussing geometric transitions, and use this to construct examples of transitions relevant to geometric topology. In particular, we will see a transition between hyperbolic and de Sitter geometry which does not occur within real projective geometry, and a transition of complex hyperbolic geometry which does not occur within complex projective space.
