On conformal Komar currents in LRS spacetimes

Abbas M. Sherif

For locally rotationally symmetric (LRS) spacetimes, we construct two equivalent forms of the Komar current derived from a conformal Killing vector. One is a kinematic construction…

Instability of marginally outer trapped surfaces from initial data set symmetry

Abbas M. Sherif

Let $(Σ ~, h_{ab}, K_{ab})$ be an initial data set and let $x^{a}$ be a symmetry vector of $Σ ~$ . Consider a MOTS $S$ in $Σ ~$ and let the symmetry vector be deco…
