See there for background and context.

This entry here is about the fact and its derivation that the partition function of a (2,1)-dimensional Euclidean field theories? is a modular form.

Idea

As described at (2,1)-dimensional Euclidean field theories and tmf, the idea is that (2,1)-dimensional Euclidean field theories? are a geometric model for tmf cohomology theory.

While there is no complete proof of this so far, here we discuss the construction and proof – due to Stephan Stolz and Peter Teichner – for the situation over the point: the partition function of a (2|1)(2|1)-dimensional EFT is a modular form. Hence (2|1)(2|1)-dimensional EFTs do yield the correct cohomology ring of tmf over the point.
