N-Dimensional FRW Dust Filled Universe with Time Dependent Λ(t) in Creation Field Theory of Gravitation

N-dimensional FRW cosmological model in Hoyle-Narlikar's creation field theory of gravitation has been studied, when the universe is filled with dust distribution. To get the deterministic solution, the cosmological constant ) (t  is considered as a time dependent function of cosmic time t i.e. 2 1 R   , where R is a scale factor. The physical aspects of the model are also studied.
