Existence of solutions for a degenerate seawater intrusion problem

open access: yesElectronic Journal of Differential Equations, 2005
We study a seawater intrusion problem in a confined aquifer. This process can be formulated as a coupled system of partial differential equations which includes an elliptic and a degenerate parabolic equation.

A boundary element and radial basis function approximation method for a second order elliptic partial differential equation with general variable coefficients

open access: yesEngineering Reports, 2019
A numerical method based on boundary integral equation and radial basis function approximation is presented for solving boundary value problems governed by a second‐order elliptic partial differential equation with variable coefficients.

Finite Difference Approximation for Linear Stochastic Partial Differential Equations with Method of Lines [PDF]

open access: yes
A stochastic partial differential equation, or SPDE, describes the dynamics of a stochastic process defined on a space-time continuum. This paper provides a new method for solving SPDEs based on the method of lines (MOL).

Completeness theorems: Fichera's fundamental results and some new contributions

open access: yesLe Matematiche, 2007
After recalling Fichera’s fundamental results in the study of the problem of the completeness of particular solutions of a partial differential equation, we give some new completeness theorem.
