Abstract

Recently Hořava proposed a renormalizable gravity theory in (eb) four dimensions which reduces to (e&eb) Einstein gravity with (e&eb) a non-vanishing cosmological constant in IR but with (e&eb) improved UV behaviors. Here, authors study an IR modification which breaks ``softly'' (e) the detailed balance condition in (eb) Hořava model and allows (eb) the asymptotically flat limit as well. Authors obtain the black hole and cosmological solutions for ``arbitrary'' cosmological constant that represent (eb) the analogs of the standard Schwarzschild-(A)dS solutions which can be asymptotically (A)dS as well as flat and authors discuss their thermodynamical properties. They also obtain solutions for (e) FRW metric with (e&eb) an arbitrary cosmological constant. Authors study its implication to (e&eb) the dark energy and find that it seems to be consistent with..
