SUMMARY:Non-invertible Symmetries of 2d Non-Linear Sigma Models - Max Vel

DESCRIPTION:Global symmetries can be generalised to transformations genera
 ted by topological operators\, including cases in which this operator does
  not have an inverse. A family of such topological operators are related t
 o dualities via the procedure of half-space gauging. I will discuss the co
 nstruction of non-invertible defects based on T-duality in two dimensions\
 , generalising the well-known case of the free compact boson to any Non-Li
 near Sigma Model (NLSM) with Wess-Zumino term which is T-dualisable. I wil
 l discuss how these symmetries can be used to constrain renormalisation gr
 oup flows\, and their fate in String Theory.
