Bianchi Type-I Universe Models with Nonlinear Viscosity
  In this paper we study the evolution of spatially homogeneous and anisotropic
Bianchi type-I Universe models with the cosmological constant, \Lambda, and
filled with nonlinear viscous fluid. The dynamical equations for these models
are obtained and solved for some special cases. We calculate the statefinder
parameters for the models and display them in the s-r-plane.
