Insensitizing controls for a semilinear heat equation with a superlinear nonlinearity
This Note is concerned with the existence of insensitizing controls for a semilinear heat equation when we consider nonlinearities that behave superlinearly at infinity. We prove the existence of a control insensitizing the L2−norm of the observation of the solution in an open subset O of the consid...

| Sumario: | This Note is concerned with the existence of insensitizing controls for a semilinear heat equation when we consider nonlinearities that behave superlinearly at infinity. We prove the existence of a control insensitizing the L2−norm of the observation of the solution in an open subset O of the considered domain under appropriate assumptions on the nonlinear term f(y) and the second member ξ of the equation. The proof uses global Carleman estimates, parabolic regularity and a fixed point argument. |
