The consistent growth of urban areas demands reflection on critical management issues such as water. The scientific literature suggests that large water problems occur as a result of lack of governance rather than physical scarcity (Pahl-Wostl, et al., 2012). It should also be recognized that government policies for water management and governance, particularly in developing countries, have lit...

Generalized Vaidya Solutions

A large family of solutions, representing, in general, spherically symmetric Type II fluid, is presented, which includes most of the known solutions to the Einstein field equations, such as, the monopolede Sitter-charged Vaidya ones. PACS numbers: 04.20Jb, 04.40.+c. ∗e-mail address: [email protected] 1 In 1951, Vaidya [1] found a solution that represents an imploding (exploding) null dust f...

Generalized Weyl Solutions

It was shown by Weyl that the general static axisymmetric solution of the vacuum Einstein equations in four dimensions is given in terms of a single axisymmetric solution of the Laplace equation in three-dimensional flat space. Weyl’s construction is generalized here to arbitrary dimension D ≥ 4. The general solution of the D-dimensional vacuum Einstein equations that admits D− 2 orthogonal com...
