Second boundary value problem

One of the boundary value problems (cf. Boundary value problem, partial differential equations) for partial differential equations. For example, let there be given a second-order elliptic equation

(*)

where , , in a bounded domain , with a normal at each point of the boundary . The second boundary value problem for equation (*) in is the following problem: Out of the set of all solutions of equation (*), isolate those solutions which have, at all boundary points, derivatives with respect to the interior normal and which satisfy the condition

where is a given function. The second boundary value problem is also known as the Neumann problem.
