Boundary-Value Problems and Applications,-value problems. Mathematically, a boundary-value problem is finding a function which satisfies a given partial differential equation and particular boundary conditions. Physically speaking, the problem is independent of time, involving only space coordinates. Just as initial-value problems are asso

,Green’s Functions and Boundary-Value Problems,nd engineering science. The linear superposition principle is one of the most elegant and effective methods to represent solutions of boundary-value problems in terms of an auxiliary function known as .. Such a function was first introduced by George Green as early as 1828. Subsequently, the method
