Wilsonian renormalization group properties of a novel non-critical cosmological string configuration

TL;DR

This paper demonstrates that a specific non-critical string cosmological model with dilaton and graviton backgrounds is an infrared stable fixed point of a Wilsonian renormalization group equation, revealing its stability properties.

Contribution

It introduces a novel non-critical string cosmological configuration and establishes its stability as a fixed point within the Wilsonian renormalization framework.

Findings

The configuration is an exact solution in non-critical string theory.

It is shown to be an infrared stable fixed point.

The results connect string cosmology with renormalization group analysis.

Abstract

We show that an exact, non-critical-string cosmological configuration of dilaton and graviton backgrounds, found in [1], constitutes an infrared stable fixed point of an exact Wilsonian renormalization group equation.
