Study of axially symmetric viscous Ricci dark energy model in Brans-Dicke theory

In this paper, we have investigated axially symmetric and anisotropic space-time filled with viscous Ricci dark energy and pressure-less dark matter in the frame-work of Brans-Dicke(BD) theory of gravitation. To solve the field equations, we use the following conditions: (i) the relationship between metric potentials which is obtained from the condition that shear scalar of the model is directly proportional to the expansion scalar, (ii) the average scale factor varies with time as a(t) = [sinh(alpha t)](1/k), and (iii) the bulk viscous coefficient (xi) as xi = xi(0) + xi(1)h + xi(2)h '', where xi(0), xi(1) and xi(2) are constants and h = H/H-0. We have studied the cosmological parameters, like bulk viscosity coefficient (xi), effective equation of state (omega(eft)), deceleration (q), Om diagnostic and cosmological planes like state-finder diagnostics {r,s} and {r,q} planes. And also, we have analyzed the physical behavior of these parameters through pictorial representation. The deceleration and effective equation of state parameters are very close to recent observational data in our model.
