KALUZA-KLEIN TYPE COSMOLOGICAL MODEL OF THE UNIVERSE WITH VACUUM ENERGY DENSITY

Abstract

In this paper by considering, the Decay law  of the form 3 , , . 2 2 constt R R R R           We generalized the result of Arbab (2001) for higher dimensional space time and observed that the cosmological constant decreases as 2 t and rate of particle creation is smaller than the steady state value. We have found an inflationary solution of the de-Sitter type with   6  3 . The present model could resolve many of standard model problems with observations and thus could become a viable candidate as an alternative model.
