摘要：
Cosmological models with time dependent displacement field in the cosmological theory based on Lyra's geometry have been discussed. Exact solutions have been obtained for a spatially flat FRW model by considering a particular form for the time dependent displacement field. We have also obtained conditions under which the matter-dominated, flat universe undergoes decelerated or accelerated expansions. Accelerated expansion of the Universe is of particular interest in view of the recent observations.
