   Abstract

The optimal control for cooperative systems involving parabolic operators with an infinite number of variables is considered. First the existence and uniqueness of the states are proved; then the necessary and sufficient condition for the control to be optimal is obtained by a set of inequalities. The control in our problems is of distributed type and is allowed to be in the Hilbert space (L2(0, T, L2(R{infty})))n.

Keywords: cooperative systems with Dirichlet and Neumann conditions; existence and uniqueness of solutions; parabolic operators with an infinite number of variables; distributed control problems.
