2D Dilaton-Maxwell Gravity as a Fixed Point of the Renormalization Group

TL;DR

This paper investigates a general 2D dilaton-Maxwell gravity model, deriving its one-loop effective action and beta-functions, and identifies specific models that serve as fixed points of the renormalization group equations.

Contribution

It introduces a general 2D dilaton-Maxwell gravity framework and finds models that are fixed points under the renormalization group flow.

Findings

Derived the one-loop effective action for the model.

Calculated the generalized beta-functions.

Identified fixed point models of the RG equations.

Abstract

A general model of dialton-Maxwell gravity in two dimensions is investigated. The corresponding one-loop effective action and the generalized $\beta$-functions are obtained. A set of models that are fixed points of the renormalization group equations are presented.
