We present the development of a two-dimensional Mixed-Hybrid Finite Element (MHFE) model for the solution of the non-linear equation of variably saturated ow in groundwater on unstructured triangular meshes. By this approach the Darcy velocity is approximated using lowest-order Raviart-Thomas (RT0)

There are occasions when a linear autonomous functional differential equation of mixed type can be reduced to a neutral or retarded equation. A necessary condition for such reducibility is shown to be that the set of solutions of the characteristic equation is bounded on the right in the complex pla
A method of using Laguerre functions is presented to obtain approximate solutions of a linear dtyerential equation of the stretched type. The solution is essentially based on the development of two new operational matrices to manipulate, respectively, the differentiation and the stretch via Laguerre
