DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/53/">
 Non-Invertible Symmetries in Calabi-Yau Conformal Field Theories</a>\nby G
 iovanni Rizi (SISSA) as part of Symmetry Seminar\n\n\nAbstract\nI will dis
 cuss non-invertible symmetries arising in 2d superconformal field theories
  corresponding to Calabi-Yau non linear sigma models. Our approach begins 
 from a particularly symmetric point in the conformal manifold of the theor
 y\, the Gepner point. Here we are able to study in detail the supersymmetr
 ic topological defect lines and show that many exactly marginal deformatio
 ns preserve a subcategory of the symmetry at the Gepner point. This constr
 uction provides examples of continuous families of irrational (and interac
 ting) CFTs with non-invertible symmetries. Finally I will discuss some of 
 the constraints those symmetries imply on correlation functions.\n\nBased 
 on 2312.17308 with Clay Córdova.\n
