SUMMARY:Topological modular forms and bilinear forms - Lennart Meier (Univ
 ersiteit Utrecht)

DESCRIPTION:Classically\, theta functions are modular forms associated to 
 certain integral bilinear forms. Topological modular forms (TMF) are a rin
 g spectrum refining the classical ring of modular forms. I will explain in
  this talk how to utilize equivariant TMF to associate to every integral b
 ilinear form an element in pi_*TMF.&nbsp\;\nThis is based on joint work wi
 th David Gepner\, Sergei Gukov\, Slava Krushkal and Du Pei.\n&nbsp\;
