Continuity properties of stationary points of quadratic functionals in hilbert space
Rouben Rostamian · Numerical Functional Analysis and Optimization · 1981
Sufficient conditions are obtained for a weak type of continuity of stationary points of quadratic functional in Hilbert space with respect to perturbations of the operator defining the functional. The setting and assumptions are directed towards the study of some boundary value problems in the theory of linear elasticity.
