Genus two virasoro correlation functions for vertex operator algebras
Tuite, Michael P.; Gilroy, Thomas (2016-12-06)We consider all genus two correlation functions for the Virasoro vacuum descendants of a vertex operator algebra. These are described in terms of explicit generating functions that can be combinatorially expressed in terms ... -
Genus two zhu theory for vertex operator algebras
Tuite, Michael P.; Gilroy, Thomas (2016-10-27)We consider correlation functions for a vertex operator algebra on a genus two Riemann surface formed by sewing two tori together. We describe a generalisation of genus one Zhu recursion where we express an arbitrary genus ...
