Separable Reduction of Metric Regularity Properties

Chapter
Part of the Springer Optimization and Its Applications book series (SOIA, volume 87)

Abstract

We show that for a set-valued mapping F: XY between Banach spaces the property of metric regularity near a point of its graph is separably determined in the sense that it holds, provided for any separable subspaces L 0X and MY, containing the corresponding components of the point, there is a separable subspace LX containing L 0 such that the mapping whose graph is the intersection of the graph of F with L × M (restriction of F to L × M) is metrically regular near the same point. Moreover, it is shown that the rates of regularity of the mapping near the point can be recovered from the rates of such restrictions.
