On uniform regularity and strong regularity

Abstract

We investigate uniform versions of (metric) regularity and strong (metric) regularity on compact subsets of Banach spaces, in particular, along continuous paths. These two properties turn out to play a key role in analyzing path-following schemes for tracking a solution trajectory of a parametric generalized equation or, more generally, of a differential generalized equation (DGE). The latter model allows us to describe in a unified way several problems in control and optimization such as differential variational inequalities and control systems with state constraints. We study two inexact path-following methods for DGEs having the order of the grid error and , respectively. We provide numerical experiments, comparing the schemes derived, for simple problems arising in physics. Finally, we study metric regularity of mappings associated with a particular case of the DGE arising in control theory. We establish the relationship between the pointwise version of this property and its counterpart in function spaces.

On the Existence of Lipschitz Continuous Optimal Feedback Control

“…Our further analysis is based on the following version of Robinson's implicit function theorem. It was first stated as [6, Theorem 5G.3] 1 and then in corrected form as Theorem 3.2 in [2] (see also [3,Theorem 2…”

Metric Regularity Relative to a Cone

“…Undoubtedly, stability of the solutions of (1.1) plays an important role and has attracted over the recent years a large number of contibutions. We refer the reader to the monographs [3,5,6,9,19,22,24,27], to the recent publications [7,8,10] and the references therein.…”
