Twisted S-Duality
Surya Raghavendran, Philsang Yoo
We study an SL(2, Z) symmetry of a variant of BCOV theory in three complex dimensions. Using conjectural descriptions of twists of superstrings in terms of topological strings, we…

Minimal models for minimal BCOV theories
Surya Raghavendran, Philsang Yoo
Minimal BCOV theory is a classical field theory which describes a subclass of deformations of the category of perfect complexes on a Calabi-Yau variety. We compute minimal models f…

Local superconformal algebras
Fabian Hahner, Surya Raghavendran, Ingmar Saberi +1
Given a supermanifold equipped with an odd distribution of maximal dimension and constant symbol, we construct the formal moduli problem of deformations of the distribution. This m…
