The partition function of 2d string theory

High Energy Physics - Theory 2011-10-11 v1

Abstract

We derive a compact and explicit expression for the generating functional of all correlation functions of tachyon operators in 2D string theory. This expression makes manifest relations of the c=1c=1 system to KP flow and W1+W_{1+\infty} constraints. Moreover we derive a Kontsevich-Penner integral representation of this generating functional.
