Some geometric properties of generalized $\varphi$-vacuum static spaces

Differential Geometry 2025-09-08 v1

Abstract

In this paper we study the geometry of generalized φ\varphi-vacuum static spaces, proving estimates for the φ\varphi-scalar curvature and for the first eigenvalue of the Jacobi operator, and also rigidity under various geometric assumptions; in particular, we prove a result related to the famous Cosmic no-hair conjecture of Boucher, Gibbons and Horowitz.
