Abstract:We establish the existence of an optimal ``state-control'' pair for an optimal control problem of Lagrange type, monitored by a nonlinear elliptic partial equation involving nonmonotone nonlinearities.
Keywords: Sobolev embedding theorem, Novikov's theorem, Aumann's theorem, pseudomonotone operator, property ($M$), nonlinear elliptic equation
