DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMULANTS/15/
 ">Multiplicity-at-most-one theorem for GSpin and GPin</a>\nby Shuichiro  T
 akeda (University of Missouri) as part of Queen Mary University of London 
 Algebra and Number Theory Seminar\n\n\nAbstract\nLet V be a quadratic spac
 e over a nonarchimedean local field of characteristic 0. The orthogonal gr
 oup O(V) and the special orthogonal group SO(V) have a unique nontrivial G
 L_1 -extension called GPin(V) and GSpin(V)\, respectively. Let W\\subseteq
  V be a subspace of codimension 1.  Then there are natural inclusions GPin
 (W)\\subseteq GPin(V) and GSpin(W)\\subseteq GSpin(V). One can then consid
 er the Gan-Gross-Prasad (GGP) periods for GPin and GSpin. In this talk\,  
 I will talk about the multiplicity-at-most-one theorem for the local GGP p
 eriods for GPin and GSpin.\n
