We prove that a vacuum static space admitting a non-trivial gradient conformal vector field is isometric to a Euclidean space or to a warped product $\mathrm{I}\times_\varphi\mathfrak{L}^{m-1}$ of an interval $\mathrm{I}$ and an Einstein manifold $\mathfrak{L}^{m-1}$, provided that scalar curvature of $\mathfrak{L}^{m-1}$ is constant.

Abstract

The purpose of this work is to study the conformal geometry of vacuum static spaces with a constant scalar curvature, which corresponds to an interesting generalization of the critical point of the equation. We prove that a vacuum static space admitting a non-trivial gradient conformal vector field is isometric to a Euclidean space or to a warped product $\mathrm{I}\times_\varphi\mathfrak{L}^{m-1}$ of an interval $\mathrm{I}$ and an Einstein manifold $\mathfrak{L}^{m-1}$, provided that scalar curvature of $\mathfrak{L}^{m-1}$ is constant.
