Constructing Globally Stable Dark Energy Models from Stability Requirements
This article introduces a stability-driven approach to constructing $F(R)$ dark energy models. By studying the functional properties of $F_R(R)$, this work identifies the sigmoid structure underlying the Appleby–Battye model, develops new globally stable model families, and discusses their implications for dark energy–inflation unification.
