Rotating Bowen-York initial data with a positive cosmological constant
Patryk Mach, Jerzy Knopik
A generalization of the Bowen-York initial data to the case with a positive cosmological constant is investigated. We follow the construction presented recently by Bizoń, Pletka an…

The shape of a rapidly rotating polytrope with index unity
Jerzy Knopik, Patryk Mach, Andrzej Odrzywolek
We show that the solutions obtained in the paper `An exact solution for arbitrarily rotating gaseous polytropes with index unity' by Kong, Zhang, and Schubert represent only approx…

General-relativistic rotation laws in rotating fluid bodies: constant linear velocity
Jerzy Knopik, Patryk Mach, Edward Malec
New rotation laws have been recently found for general-relativistic self-gravitating stationary fluids. It was not clear whether they apply to systems rotating with a constant line…
