# Boundary reparametrizations as additional moduli for the string propagator

## Abstract

Analyzing the Polyakov integral on surfaces with boundaries, where the values of the string variables are fixed, the authors use the observation that there are more holomorphic quadratic differentials besides those obtained as restrictions from the Schottky double. They are naturally related to boundary reparametrizations. The corresponding additional moduli are used to express the integration over metrics. Some details are given for the vacuum functional and the propagator.
