"String structures and parametrized field theories"


Distler and Sharpe have proposed a string theory, whose elliptic genus is conjecturally one studied earlier by Liu, and which mixes the Witten genus and the characters of representations of loop groups. I will describe some progress towards understanding this theory, which is a living example of a quantum field theory parametrized over a base. In particular, I will discuss a related parametrized topological field theory and its relationship to string structures.
