Bosonization Methods in String Theory

摘要

The use of bosonization/fermionization techniques to convert non-linear operators of the dual, is discussed. Non abelian bosonization to the case where the central charge of the Kac-Moody algebra is not unity, is generalized. In particular, using this generalization of non-abelian bosonization, the bosonic string vertex of the compactified theory turns out to be fundamental field of the fermionic theory, or bound states of it thus permiting explicit computations easily.
