DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/37/">H
 olomorphic CFTs and topological modular forms</a>\nby Du Pei (Harvard) as 
 part of NHETC Seminar\n\n\nAbstract\nThe theory of topological modular for
 ms leads to many interesting constraints and predictions for two-dimension
 al quantum field theories. In this talk\, I will show that a conjecture by
  Segal\, Stolz and Teichner requires the constant term of the partition fu
 nction of a bosonic holomorphic CFTs to be divisible by specific integers 
 determined by the central charge. We verify this constraint in large class
 es of physical examples\, and rule out the existence of an infinite set of
  "extremal CFTs"\, including those with central charges c = 48\, 72\, 96 a
 nd 120.\n
