摘要：

A Kaluza-Klein (KK) type of inhomogeneous cosmological model is obtained with a matter field in the form of a dust. Under suitable conditions our solution either reduces to a recent inhomogeneous model of the present authors or to some other well known homogeneous KK cosmologies. It is observed that, depending on initial conditions, both the spaces either expand or as the usual scale expands the extra scale contracts exhibiting the desirable feature of dimensional reduction. Further, our spacetime may give wormhole configuration at the classical level. It is also found that aside from the singularity at the big bang the model is spatially nonsingular.
