New spinorial approach to mass inequalities for black holes in general relativity
Jarosław Kopiński, Juan A. Valiente Kroon
A new spinorial strategy for the construction of geometric inequalities involving the Arnowitt-Deser-Misner (ADM) mass of black hole systems in general relativity is presented. Thi…

Optical properties of self-similar structure in Lemaitre-Tolman-Bondi model
Jarosław Kopiński
We explore the effects coming from the nested structures on propagation of radial light rays going through them in the simple self-similar configuration containing pairs of voids a…
