Necessary conditions for elliptic control problems
with control and state constraints

Let
be a bounded domain
with piecewise smooth boundary
.
The derivative in the direction of the outward unit normal of
will be denoted by
.
Suppose that the boundary is partioned as
with disjoints sets
that consist of finitely
many connected components.
