Abstract

We consider the following problems: minimize

$$I_n (u) = |u - \hat u|^p + |L_n u - \hat y|^p , n \geqslant 0,$$

whereL n are equibounded linear operators. If we callu n,u 0 the minimum points ofI n, we characterize the strong convergence ofu n tou 0 in terms of the pointwise convergence ofL n and their adjoint operatorsL n* toL 0 andL 0*, respectively. Then, we apply this result to the case of a problem governed by a linear differential equation. Finally, we conclude by studying perturbations of an abstract constrained minimum problem.
