General-relativistic rotation: self-gravitating fluid tori in motion around black holes

Janusz Karkowski, Wojciech Kulczycki, Patryk Mach +3

We obtain from the first principles a general-relativistic Keplerian rotation law for self-gravitating disks around spinning black holes. This is an extension of a former rotation…

Toroidal trapped surfaces and isoperimetric inequalities

Janusz Karkowski, Patryk Mach, Edward Malec +2

We analytically construct an infinite number of trapped toroids in spherically symmetric Cauchy hypersurfaces of the Einstein equations. We focus on initial data which represent "c…
