SUMMARY:Holomorphic blocks in 3 dimensions - Sara Pasquetti (University of
  Surrey)

DESCRIPTION:We show that sphere partition functions and indices of 3 dimen
 sional\, N = 2\, gauge theories can be decomposed into a sum of products o
 f a universal set of holomorphic blocks. The blocks count BPS states of a 
 theory on R2 x S1 and are in one-to-one correspondence with the theory's m
 assive vacua. The blocks turn out to have a wealth of surprising propertie
 s such as a Stokes phenomenon and have interesting dual interpretations in
  analytically continued Chern-Simons theory and open topological strings.
