Subhash D. Tade, Anisa P. M. Ahmad, R. V. V. Saraykar


In this paper, we have studied Kaluza-Klein universe for quark matter coupled with the string cloud and domain walls in the context of Lyra geometry. The field equations have been solved by using proportionality relation between the shear scalar  and the scalar expansion , variation law for generalized Hubble’s parameter formulated by Berman (Nuovo Cimento B, 74, 2, 182-186, 1983) which yields constant deceleration parameter and time varying displacement field . Some physical aspects of the solutions, thus obtained, are also discussed.
