set X to the Euclidean space of which X is a subset has at least one stationary point, being a point in X at which the … stationary point. In this paper we refine the concept of stationary point by perturbing simultaneously both the set X and the … solution concept. In case a stationary point is the limit of a sequence of perturbed solutions on a sequence of sets converging …
