SUMMARY:Going beyond rigidity in tensor categories - Simon Wood (Cardiff U
 niversity)
DTSTART:20240620T124500Z

DESCRIPTION:Rigid (or even modular) tensor categories enjoy many nice prop
 erties and have hence been a topic of intense study. However\, given some 
 specific source of tensor categories such as the representation theory of 
 vertex algebras (or conformal field theory) it can be extremely difficult 
 to prove rigidity. In fact such tensor categories need not be rigid. They 
 may\, nevertheless\, enjoy a weaker notion of duality called Grothendieck-
 Verdier duality\, which will be the focus of this talk. I will be presenti
 ng a number of natural examples and recent results.&nbsp\;
