KALUZA-KLEIN TILTED COSMOLOGICAL MODEL IN LYRA GEOMETRY COUPLED WITH AND WITHOUT MAGNETIC FIELD

Abstract

In this paper we have investigated Kaluza-Klein Tilted Bianchi type –I cosmological model in the presence as well as in the absence of magnetic field by the frame work of Lyra geometry. Exact solutions to the field equations are derived when the metric potentials are functions of cosmic time only. From the physical and geometrical properties of the solutions we find that in the absence of mag netic field pressure,energy density,heat conduction,scalar expansion and tilt angles are constant initially at T=0 and decreases as cosmic time increase. Due to the presence of magnetic field tilt angle and heat conduction vectors are initially constant and rapidly increases when the cosmic time of universe increase.
