Malec–O Murchadha conjecture. Given any constant mean curvature $H$, the Kruskal extension can be foliated by the TSS-CMC hypersurfaces $\{\Sigma_H\}$. The paper presents this as t…

Let $\Sigma$ be a spacelike $2$-surface in Schwarzschild spacetime, and let $\vec{J}$ denote its dual mean curvature vector. Suppose that the past null hypersurface generated by…
