Chaos in spatially homogeneous Hořava-Lifshitz subcritical cosmologies

Abstract

We consider spatially homogeneous models in Hořava-Lifshitz (HL) gravity that perturbs General Relativity (GR) by a parameter $v\in (0,1)$ such that GR occurs at $v=1/2$. We prove that the induced Kasner map is chaotic for a broad class of modified HL gravity models, when $v\in (0,1/2)$, despite the fact that the Kasner map is multivalued in such subcritical regime.
