Evolution of Generalized Brans–Dicke Parameter within a Superbounce Scenario

We have studied a superbounce scenario in set up of Brans-Dicke (BD) theory. The BD parameter is considered to be time dependent and assumed evolve with the scalar field. In scenario, model bounces at an epoch corresponding Big Crunch provided ekpyrotic phase continues until that time. Within given we investigate evolution for different equations state. chose axially symmetric metric has axial symmetry along x-axis. incorporate anisotropic expansion effect. effect asymmetric on evolving non-evolving part investigated.
