AbstractThe general exact solution of the gravitational field equations for a homogeneous flat Friedmann-Robertson-Walker universe filled with a causal bulk viscous fluid with bulk viscosity coefficient proportional to the Hubble function is obtained in the framework of the full causal Israel-Stewart-Hiscock theory. The general solution of the field equations is represented in an exact closed parametric form and corresponds to a transition between two Minkowskian space-times connected by an inflationary period. The evolution of the temperature, entropy, deceleration parameter and bulk viscosity coefficient are considered in the general case. Particular solutions corresponding to a particular choice of parameters and leading to a non-inflationary evolution of the universe are presented too.
