Thirring Strings: Use of Generalized Nonabelian Bosonization Techniques

Abstract

In the last few years strings have been proved to be extremely important objects for describing fundamental interactions.¹ However, there are many technical difficulties in the description of string dynamics, and, perhaps, one of the most relevant aspects to be fully understood is compactification. It is my aim to relate the string defined on a compactified space time to a fermionic model in such a way that, in the latter, complicated and important operators, such as the vertices,^1,2 turn out to be elementary fields. Therefore, correlators involving vertices, which are nonlinear in the string field variables, will turn out to be linear in terms of fermionic variables.
