Bounce scenarios in the Sotiriou-Visser-Weinfurtner generalization of the projectable Horava-Lifshitz gravity

The occurrence of a bounce in the FRW cosmology requires modifications of general relativity. An example of such a modification is the recently proposed Horava-Lifshitz (HL) theory of gravity, which includes a 'dark radiation' term with a negative coefficient in the analog of the Friedmann equation. A modification of the HL gravity, relaxing the 'detailed-balance' condition, brings additional terms to the equations of motion, corresponding to stiff matter. This paper presents a comparison of the phase structure of the original and modified Horava cosmology. Special attention is paid to the analysis of a wide range of the bouncing solution, appearing in both versions of the Horava theory.
