| Abstract: | The evolution of a probe D-brane in the p-brane background is considered. The anisotropic evolution of the world-volume of the D-brane with a given topology of a world-volume
in the form of a direct product of a n-dimensional flat space and (3 − n)-dimensional sphere is formulated. In this case the anisotropy is described with the aid of two parameters (Hubble parameters)
The special case of this evolution, namely the isotropic evolution corresponds to equality of these two parameters. In the
latter case the masses and charges of the background p-branes are obtained. |
