Kinematic and statistical inconsistencies of Hořava–Lifshitz cosmology

Does emergent scenario in Hořava–Lifshitz gravity demand a ghost field?

“…Ḣ − k a 2 = −4π(p + ρ) (30) and equation (27) for the Horizon temperature, the total entropy variation takes the form;…”

“…Also the dynamics and the viability of these versions has been discussed in this review. Further in [27] the authors have investigated the limits imposed by observations on the minimal paradigm of HL in the background of homogeneous and isotropic space-time. They have found statistical inconsistencies of the model, ruling out HL paradigm at the level of background cosmology.…”

Global dynamics of Hořava–Lifshitz cosmology with non-zero curvature and a wide range of potentials

“…In recent years Hořava [1] proposed a spacetime asymmetric gravitational theory similar to Lifshitz's scalar field theory, also known as Hořava-Lifshitz gravity. This theory has inspired a great deal of research for its applications in cosmology and black hole physics (see [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] or the review articles [19,20] and the references therein).…”

Extended analysis for the evolution of the cosmological history in Einstein-aether scalar field theory

“…Hořava-Lifshitz is a renormalization theory with consistent ultra-violet behavior exhibiting an anisotropic Lifshitz scaling between time and space [7]. Hořava-Lifshitz theory has various applications in gravitational theories from cosmological studies until compact stars [8][9][10][11][12][13][14][15].…”
