The class of homogeneous Siklos space-times is considered from algebraic point of view and the generalized Ricci solitons are completely classified.

Wavelet-Galerkin method is a powerful tool for the numerical solution of partial differential equations. The main aim of this paper is, by combining the finite difference method with the wavelet-Galerkin method, to solve some first order partial differential equation and we also show that this method can be useful for analytical solution of such equations.
