Higher Dimensional Szekeres' Space-time in Brans-Dicke Scalar Tensor Theory
The generalized Szekeres family of solution for quasi-spherical space-time of
higher dimensions are obtained in the scalar tensor theory of gravitation.
Brans-Dicke field equations expressed in Dicke's revised units are exhaustively
solved for all the subfamilies of the said family. A particular group of
solutions may also be interpreted as due to the presence of the so-called
C-field of Hoyle and Narlikar and for a chosen sign of the coupling parameter.
The models show either expansion from a big bang type of singularity or a
collapse with the turning point at a lower bound. There is one particular case
which starts from the big bang, reaches a maximum and collapses with the in
course of time to a crunch
