Continuous Virasoro algebra in open string field theory

Abstract

It is known that the Takahashi–Tanimoto identity-based solution in open string field theory derives a kineticoperator which is a sum of twisted Virasoro generators. Applying the infinite circumstance description of conformalfield theory, we derive continuous Virasoro algebra associated with the kinetic operator. Mode expansions of Virasorogenerators and the modified BRST charge are given.
