Abstract

V originále

Generalizing the results obtained by Semerák, O. (1993), Stationary Frames in the Kerr Field, Gen. Relativity Gravitation, 10(1045), an interesting difference between the Kerr and Kerr-de Sitter geometries has been found. In the case of freely falling stationary observers located on the axis of symmetry, rotating supermassive black holes (not necessarily fast rotating) behave differently from the same bodies for which the present value of cosmological constant is not included. An interesting family of "freely falling stationary observers" is described.
