SUMMARY:VOAs and Superconformal Field Theory in Four Dimensions - Chris Be
 em (Oxford)
DTSTART:20190509T140000Z
DTEND:20190509T150000Z
UID:TALK123727@talks.cam.ac.uk
CONTACT:Dr. Carl Turner
DESCRIPTION:I will describe an extensive correspondence between N=2 superc
 onformal field theories in four dimensions and vertex operator algebras\, 
 i.e.\, chiral algebras. After recalling essential notions of the algebraic
  structure of four-dimensional SCFTs\, I will outline the origins of the V
 OA structure. I will then give an overview of the VOA/SCFT dictionary\, wh
 ich is by now quite elaborate. With sufficient time\, I will describe some
  main results and conjectures associated with this program\, such as modul
 arity properties of the superconformal index and intricate unitarity bound
 s for theories with continuous global symmetries.
