LRS Bianchi type-II cosmological model for perfect fluid distribution in Lyra geometry (Q2888353)

The authors give locally rotationally symmetric (LRS) solutions of Bianchi type II and interpret them as cosmological models for perfect fluid distribution in Lyra geometry. The latter refers to a theory of gravity proposed by Gerhard Lyra in 1951. They assume that shear is proportional to expansion to simplify the equations.NEWLINENEWLINEFor papers on similar topics see also [the authors, Int. J. Theor.
