Irreversibility of the Renormalization Group Flow in Two Dimensional Quantum Gravity

High Energy Physics - Theory 2015-06-26 v1

Abstract

We argue that the torus partition sum in 2d2d (super) gravity, which counts physical states in the theory, is a decreasing function of the renormalization group scale. As an application we chart the space of (c^1)(\hat c\leq1) c1c\leq1 models coupled to (super) gravity, confirming and extending ideas due to A. Zamolodchikov, and discuss briefly string theory, where our results imply that the number of degrees of freedom decreases with time.
