Abstract: In this paper, we have developed a new cosmological model in Einstein’s modified gravity theory using two types of modification: (i) Geometrical modification, in which we have used Lyra’s geometry in the left-hand side of the… read more here.

DOI: 10.1142/s0219887818501943
Abstract: The paper deals with the investigation of a homogeneous and anisotropic space-time described by Bianchi type-III metric with perfect fluid in Lyra geometry setting. Exact solutions of Einstein’s field equations have been obtained under the… read more here.
