Interaction of fluids described through relative motion and application to Bianchi type-I spacetimes
Peter Mészáros, Daniel Račko
We derive the stress-energy tensor for a pair of fluids with a novel form of interaction that depends on the relative velocity of volume elements of the two fluids. The interaction…

Properties of generalized Schwarzschild spacetimes with extra dimensions
Peter Mészáros
We show that an ansatz for dimensional static spacetime with spherical symmetry in three dimensions and Euclidean symmetry in dimensions, parametrized by only one funct…
