DESCRIPTION:[b]Speaker: Lennart Meier[/b] (Utrecht University) [nl][nl]\n[
 b]Abstract:[/b][nl]\nPartition functions of 2-dimensional supersymmetric 
 quantum field theories (SQFTs) are modular forms. Prominent examples are 
 the theta functions arising from lattice conformal field theories. A phil
 osophy due to Segal\, Stolz and Teichner says that SQFTs allow a refineme
 nt of the partition function to *topological modular forms*. In our talk\
 , we will give a short introduction to this theory and discuss how to ref
 ine theta functions to topological modular forms. If time allows\, we wil
 l discuss the relationship to a potential new TQFT in dimension 3+1. \nTh
 is is based on joint work with Sergei Gukov\, Slava Krushkal and Du Pei.
