Abstract

As a candidate of quantum gravity in ultrahigh energy, the -dimensional Hořava-Lifshitz (HL) gravity with critical exponent , indicates anisotropy between time and space at short distance. In the paper, we investigate the most general Hořava-Lifshitz gravity in arbitrary spatial dimension , with a generic dynamical Ricci flow parameter and a detailed balance violation parameter . In arbitrary dimensional generalized HL gravity with at long distance, we study the topological neutral black hole solutions with general in HL, as well as the topological charged black holes with in HL. The HL gravity in the Lagrangian formulation is adopted, while in the Hamiltonian formulation, it reduces to DiracDe Witt's canonical gravity with . In particular, the topological charged black holes in HL, HL, HL and HL with are solved. Their asymptotical behaviors near the infinite boundary and near the horizon are explored respectively. We also study the behavior of the topological black holes in the -dimensional HL gravity with gauge field in the zero temperature limit and finite temperature limit, respectively. Thermodynamics of the topological charged black holes with , including temperature, entropy, heat capacity, and free energy are evaluated.

51 pages, published version. The theoretical framework of z=d HL gravity is set up, and higher curvature terms in spatial dimension become relevant at UV fixed point. Lovelock term, conformal term, new massive term, and Chern-Simons term with different critical exponent z are studied
