WebTools. In mathematics, a Dirichlet problem is the problem of finding a function which solves a specified partial differential equation (PDE) in the interior of a given region that takes prescribed values on the boundary of the region. The Dirichlet problem can be solved for many PDEs, although originally it was posed for Laplace's equation. WebRepresentations of the solutions to the principal boundary value problems of mathematical physics, can always be obtained provided certain boundary integral equations can be solved. ... and Neumann problems for the Laplace equation.
