TH String Theory Seminar

Elliptic genera and mock modular forms

by Jan Troost (LPTENS, Paris)

Tuesday, 3 December 2013 from to (Europe/Zurich)
at CERN ( 4-2-011 - TH common room )
We discuss elliptic genera of supersymmetric two-dimensional conformal field theories with continuous spectra. We argue that they consist of a mock modular term, and a non-holomorphic modular completion. We illustrate the general arguments with a large class of examples, computed using conformal field theory, string theory and localization techniques. Finally, we discuss applications.
