Abstract

Abstract We consider, in normal-gauge Lyra’s geometry, evolution of a homogeneous isotropic universe in a gravitational model involving only the standard matter in interaction with a displacement vector field ϕμ. Considering both constant and time-dependent displacement vector fields we show that the observed cosmic acceleration could be explained without considering an alien energy component with a negative pressure.
