Viscous generalized Chaplygin gas model in Brans-Dicke theory

The Kantowski-Sachs cosmological model for viscous generalized Chaplygin gas has been investigated in the Brans-Dicke theory of gravitation. To determine the solutions of field equations, we have considered the power-law relation for the average scale factor. We have computed some cosmological parameters and discussed their physical importance. Furthermore, we have discussed the nature of statefinder and Om diagnostics in our model. It is also worth noting that the conclusions of the cosmological parameter are consistent with modern observational data.
