Description
A multidimensional cosmological model describing the evolution of n Ricci-flat spaces is studied in the presence of a fluid with anisotropic pressure and bulk viscosity. The second equation of state is adopted in the form of a metric dependence of the bulk viscosity coefficients. For special sets of parameters exact solutions of Einstein equations are obtained in a Kasner-like form. Models with creation of matter, describing expansion of the external space and contraction of the internal ones, are singled out.
