Density-metric unimodular gravity: vacuum maximal symmetry
arXiv:1003.2296 · doi:10.1016/j.aop.2010.09.003
Abstract
We have investigated the vacuum maximally symmetric solutions of recently proposed density-metric unimodular gravity theory,the results are widely different from inflationary senario.The exponential dependence on time in deSitter space is substiuted by a power law. Open space-times with non-zero cosmological constant are excluded in this theory
