A Higher Dimensional Inflationary Universe in General Relativity

Abstract

A five dimensional Kaluza-Klein inflationary universe is investigated in the presence of massless scalar field with a flat potential. To get an inflationary universe a flat region in which potential V is constant is considered. Some physical and kinematical properties of the universe are also discussed.

A Higher Dimensional Cosmological Model in a Scale-Covariant Theory of Gravitation

“…Kaluza-Klein cosmological model in scale-covariant theory of gravitation is represented by (19) which is homogeneous and has no initial singularities. For the model (19), kinematical parameters are Spatial volume:…”

“…Higher dimensional cosmological models in alternative theories of gravitation with perfect fluid source and string source are of recent interest in modern cosmology as they do play an important role in the discussion of the early universe. Reddy et al [15][16][17], Reddy and Naidu [18,19] have discussed higher dimensional cosmological models in several alternative theories of gravitation. In this paper, we study a five dimensional Kaluza-Klein cosmological model with the help of Hubble's special law of variation proposed by Bermann [20].…”

Kaluza-Klein radiating model in a general scalar-tensor theory

“…Several investigations have been made in higher dimensional cosmology in the framework of different scalartensor theories of gravitation. In particular, , 2008, 2009 , have studied the higher dimensional string cosmological models in BransDicke and other scalar-tensor theories of gravitation.…”

Kantowaski-Sachs Inflationary Universe in General Relativity

“…While Burd and Barrow [5], Wald [18], Barrow [2], Eills and Madsen [7], Hensler [9], Chakraborty [6] studied different aspects of scalar fields in the evolution of the universe. The role of self-interacting scalar fields in inflationary cosmology has been investigated by Bhattacharjee and Baruah [4], Bali and Jain [1], Rahman et al [12], Reddy and Naidu [14], Reddy et al [13]. Very recently Reddy [15] has discussed Bianchi type-V inflationary universe in general relativity.…”
