The variational method of studying boundary value problems was discovered in midth century as the so-called Dirichlet principle of finding, in a domain, a harmonic function assuming on the boundary a given value,, which, in the class of functions being considered, yields the minimum of the Dirichlet integral. Originally, the Dirichlet principle was used only in the theory of second-order linear elliptic equations . In mathematics, an elliptic boundary value problem is a special kind of boundary value problem which can be thought of as the stable state of an evolution example, the Dirichlet problem for the Laplacian gives the eventual distribution of heat in a room several hours after the heating is turned on.. Differential equations describe a large class of natural phenomena, from the heat.

Numerical Solution of Partial Differential Equations–II This chapter discusses a few aspects of the method of the hypercircle applied to elliptic variational problems. Methods of the Rayleigh–Ritz–Galerkin type for the approximation of boundary value problems using spline basis functions and Sobolev spaces have received much attention.
