Scaling attractors for quintessence in flat universe with cosmological term

TL;DR

This paper classifies late-time attractors with scaling behavior of scalar field quintessence in a flat universe, considering the influence of a cosmological constant, and identifies conditions for exact scaling solutions.

Analyzes the influence of potential parameters and initial data.

Abstract

For evolution of flat universe, we classify late time and future attractors with scaling behavior of scalar field quintessence in the case of potential, which, at definite values of its parameters and initial data, corresponds to exact scaling in the presence of cosmological constant.
