Generalized Chaplygin Gas Models In Bianchi Type Iii Space - Time Geometry With Time Varying Bulk Viscosity, Cosmological And Gravitational Constants
This paper is devoted to study the
generalized Chaplygin gas models in Bianchi type III
space – time geometry with time varying bulk
viscosity, cosmological and gravitational constants.
We are considering the condition on metric potential
. Also to obtain
deterministic models we have considered physically
reasonable relations like p P ,
and the equation of state for generalized Chaplygin
gas given by
. A new set of solutions of
Einstein’s field equations have been obtained in
Eckart theory, truncated theory and full causal theory.
Physical behaviour of the models have been
