Query: C-field cosmological model in higher dimensions   Hoyle and Narlikar's $C$-field cosmology is extended in the framework of
higher dimensional spacetime and a class of exact solutions is obtained.
Adjusting the arbitrary constants of integration one can show that our model is
amenable to the desirable property of dimensional reduction so that the
universe ends up in an effective 4D one.Further with matter creation from the
$C$-field the mass density steadies with time and the usual bigbang singularity
is avoided. An alternative mechanism is also suggested which seems to provide
matter creation in the 4D spacetime although total matter in the 5D world
remains conserved. Quintessence phenomenon and energy conditions are also
discussed and it is found that in line with the physical requirements our model
admits a solution with a decelerating phase in the early era followed by an
accelerated expansion later. Moreover, as the contribution from the $C$-field
is made negligible a class of our solutions reduces to the previously known
higher dimensional models in the framework of Einstein's theory.
