A remark on orbit spaces of Lorentzian spaces

2023
Summary: We study the orbit space of Lorentzian spaces under the action of a connected and closed subgroup of the linear isometries. If dimension of the orbit space is bigger than two then topological characterization of the orbit space reduces to a problem in Riemannian geometry.

Metrizability of proper G-spaces and their orbit spaces

Topology and its Applications, 2021
In this paper, a \textit{\(G\)-space} \(X\) is a completely regular Hausdorff space together with a fixed continuous action \(G\times X\to X\) defined by \((g,x)\mapsto gx\) of a locally compact group \(G\) on \(X\). Recall that a \(G\)-space \(X\) is called \textit{proper} in the sense of [\textit{R. S. Palais}, Ann. Math.
