DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/65/">
 2D Non-invertible Symmetries and Anomalies from String Theory</a>\nby Xing
 yang Yu (Virginia Tech) as part of Symmetry Seminar\n\n\nAbstract\nWe inve
 stigate a string theory perspective for non-invertible symmetries in 2D QF
 Ts. In particular\, we discuss how symmetry topological field theories (Sy
 mTFTs) and anomalies of non-invertible symmetries arise from top down. Our
  primary focus is on an infinite class of 2D QFTs from Calabi-Yau 4-folds 
 probed by D1-branes. We derive 3D SymTFTs from IIB string theory and show 
 the resulting 2D QFTs can exhibit non-invertible symmetries with a wrapped
  brane origin.  These non-invertible symmetries can suffer from anomalies\
 , which are able to be translated into branes patterns ``at infinity''. Ex
 plicit examples are provided to illustrate our idea.\n
