Apparent horizons in D-dimensional Robinson–Trautman spacetime
Svítek O.
We derive the higher dimensional generalization of Penrose–Tod equation describing apparent horizons in Robinson–Trautman spacetimes. New results concerning the existence and uniqueness of its solutions in four dimensions are proven. Namely, previous results of Tod are generalized to nonvanishing cosmological constant.
