DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QTFMS/24/">V
 ertex Tube Algebras Meet Topological Defects</a>\nby Ho-Tat Lam (Universit
 y of Southern California) as part of Quantum Theories of Fields\, Matter\,
  and Strings\n\n\nAbstract\nChiral algebras and topological defects repres
 ent two complementary notions of symmetries in two-dimensional conformal f
 ield theory. In this talk\, we will explore the interplay between these tw
 o fundamental concepts. In particular\, we will address three interconnect
 ed questions: How does a chiral algebra act on the defect Hilbert spaces? 
 What happens to a chiral algebra after gauging? And how to incorporate non
 -local chiral operators into chiral algebras? In answering these questions
 \, we will reveal an intricate mathematical structure underlying two-dimen
 sional conformal field theories\, which we refer to as vertex tube algebra
 \, that generalizes both the celebrated vertex operator algebra and the tu
 be algebra familiar from the study of non-invertible symmetries.\n
