On Multidimensional Cosmology with Anisotropic Fluid: Asymptotical Acceleration and Zero Variation of G

A multidimensional cosmological model describing the dynamics of n + 1 flat factor-spaces Mi in the presence of a one-component anisotropic fluid is offered. The pressures in all spaces are proportional to the density: pi = wiρ, i = 0,. . . , n. Solutions with accelerated expansion of our 3-space M0 and zero variation of the gravitational constant G are studied. These solutions exist for two branches of the parameter w0: The first branch describes the matter with w0 > 1, the second one may contain phantom matter with w0 < − 1. It is shown that these solutions are special case of more general solutions with accelerated expansion of our 3-space M0 and asymptotically zero variation of the gravitational constant G.
