The numerical solution of some elliptic boundary value problems by integral operator methods
- 267 Downloads
An integral representation for the solution of elliptic equations of the form Δnu - P(r2)u=0, developed by Gilbert, is used to construct approximate solutions for problems of this type. Properties of the G-function, needed in the integral representation, are discussed and a numerical scheme for its computation is given. The approximate G-function is used to represent the solution and minimization techniques are used to satisfy the boundary conditions. A discussion of the practical usefulness of methods of this type is given.
