Quasi-quantum groups from Kalb-Ramond fields and magnetic amplitudes for strings on orbifolds

Abstract

We present the general form of the operators that lift the group action on the twisted sectors of a bosonic string on an orbifold M/G, in the presence of a Kalb-Ramond field strength H. These operators turn out to generate the quasi-quantum group Dω[G], introduced in the context of orbifold conformal field theory by R. Dijkgraaf, V. Pasquier and P. Roche… (More)
