Abstract

V originále

We use the so called mass function method for obtaining new exact solutions for Schwarzschild-like black holes. The mass function is algebraic invariant for general spherically symmetric metric. Rewriting Einstein equations in terms of mass function we consider Schwarzschild-like black holes. We show that Schwarzschild black holes should necessarily contain non-baryonic matter. We furthermore obtain new exact solutions for the black hole embedded into the dust matter universe.
