DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/3/">The
  isometry group of spherical quotients</a>\nby Ricardo Mendes (University 
 of Oklahoma) as part of Virtual seminar on geometry with symmetries\n\n\nA
 bstract\nA special class of Alexandrov metric spaces are the quotients $X=
 S^n/G$ of the round spheres by isometric actions of compact subgroups $G$ 
 of $O(n+1)$. We will consider the question of how to compute the isometry 
 group of such $X$\, the main result being that every element in the identi
 ty component of $\\operatorname{Isom}(X)$ lifts to a $G$-equivariant isome
 try of the sphere. The proof relies on a pair of important results about t
 he "smooth structure" of $X$.\n
