Sulla unicità della soluzione di alcuni problemi di controllo ottimo in spazi di Orlicz.

Let (E)z +A(x, y)z+B(x, y)z+C(x, y)z=U(x, y) a.e. in Δ=]0, a[×]0, b[, be a distributed parameter control process. We study the uniqueness of some optimal control problems (minimum distance and minimum effort problems) relative to ( E). We take the Orlicz space L (Δ) as the «permanent control space, whereas both the «initial control» space and the «target» space are subspaces of the Orlicz-Sobolev space W (]0, a[)× W (]0, b[).
