Renormalization Group Approach to Generalized Cosmological models

TL;DR

This paper applies the renormalization group method to analyze generalized cosmological models, identifying fixed points and their stability to understand the models' long-term behavior.

Contribution

It introduces a comprehensive renormalization group framework for generalized cosmologies, including stability analysis of fixed points, which is a novel approach in this context.

Findings

Identification of asymptotic fixed points in generalized cosmologies

Stability analysis of these fixed points

Insights into the long-term behavior of cosmological models

Abstract

We revisit here the problem of generalized cosmology using renormalization group approach. A complete analysis of these cosmologies, where specific models appear as asymptotic fixed-points, is given here along with their linearized stability analysis.
