DESCRIPTION:Conformal Field Theory at Higher Genus\, Modular Bootstrap and 
 Entanglement Entropy.\n\nTwo dimensional conformal field theories are amon
 g the most important quantum field theories: they describe important stati
 stical and condensed matter systems near criticality\, and -- while not ex
 actly solvable -- many exact techniques can be used which are not availabl
 e in higher dimensions. I will consider these theories defined on surfaces
  of genus g>1\, where the partition function of the theory can be interpre
 ted as an entanglement Renyi entropy. This leads to a fascinating relation
 ship between (higher genus) modular invariance and information theory. I w
 ill describe novel uses of higher genus modular invariance to constrain th
 e structure constants of the theory\, based on recent work with J. Cardy a
 nd H. Maxfield. I will also describe the relationship between the theory o
 f modular forms for triangle groups and entanglement entropy in two dimens
 ional CFT.\n
