DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UAANTS/35/">
 Companion forms with non-regular weights</a>\nby Zhixiang Wu (Paris-Saclay
 ) as part of University of Arizona Algebra and Number Theory Seminar\n\n\n
 Abstract\nIn general\, for an overconvergent p-adic automorphic form of a 
 definite unitary group\, there exist other p-adic automorphic forms with p
 ossibly different weights which are associated with the same Galois repres
 entation (the companion forms). Under the Taylor-Wiles hypothesis\, we det
 ermine all the companion forms whose associated Galois representations are
  generic crystalline over p and with Hodge-Tate weights possibly non-regul
 ar. This generalizes the result of Breuil-Hellmann-Schraen in regular case
 s.\n
