摘要：

We have constructed five dimensional FRW cosmological models for k = -1, 1, 0 in Lyra manifold with time dependent displacement field. The matter field is considered in the form of a perfect fluid with isotropic matter pressure. It is found that the model for k = -1 is inflationary. For k = 1, the model is inflationary for set of values of arbitrary constant a and decelerates in the standard way for another set of values of n. Moreover the concept of Lyra manifold does not exist at infinite time.
