题   目 :Supersymmetric field theories and Jacobi forms

摘   要:  Graeme Segal conjectured in the 1980's that the cohomology theory known as ellptic cohomology can be described in terms of 2-dim (conformal) field theories. Almost twenty years later, Stolz and Teichner developed Segal's idea systematically. They showed that the partition function of a 2|1 EFT (Euclidean field theory) is a modular form, which can be seen as the first step towards attacking the conjecture. We give more evidence of the conjecture by showing that the partition function of 2|2-field theories are Jacobi forms,which we believe corresponds to complex elliptic genus.
