Thick brane world model from perfect fluid

Summary: "A (1+d)-dimensional thick brane world model with varying Lambda-term is considered. The model is generalized to the case of a chain of Ricci-flat internal spaces when the matter source is an anisotropic perfect fluid. The `horizontal' part of the potential is obtained in the Newtonian approximation. In the multitemporal case (with a Lambda term) a set of equations for the potentials is presented."
