BIANCHI TYPE-I UNIVERSE MODELS WITH CONSTANT DECELERATION PARAMETER IN LYRA GEOMETRY

Abstract

In this paper, Bianchi type-I metric with constant deceleration parameter in presence of perfect fluid in the context of Lyra geometry has been considered. The Einstein field equations are solved using the condition B = Cⁿ on assuming scalar expansion is proportional to a shear scalar. The deceleration parameter q is taken as a scalar (i.e. m-1, m>0). The physical properties are discussed.
