New spinorial mass-quasilocal angular momentum inequality for initial data with marginally future trapped surface
Jarosław Kopiński, Alberto Soria, Juan A. Valiente Kroon
We prove a new geometric inequality that relates the Arnowitt-Deser-Misner mass of initial data to a quasilocal angular momentum of a marginally future trapped surface inner bounda…

Ruled surfaces in 3-dimensional Riemannian manifolds
Marco Castrillón, María Eugenia Rosado, Alberto Soria
In this work, ruled surfaces in 3-dimensional Riemannian manifolds are studied. We determine the expression for the extrinsic and sectional curvature of a parametrized ruled surfac…
