Subdifferential Calculus Rules in Convex Analysis: A Unifying Approach Via Pointwise Supremum Functions
TL;DR: A rule to calculate the subdifferential set of the pointwise supremum of an arbitrary family of convex functions defined on a real locally convex topological vector space is provided.
Journal ArticleDOI
Homotopical Stability of Isolated Critical Points of Continuous Functionals
Abstract: We give a simple proof of the so-called Potential well theorem of Ioffe and Schwartzman, estimating the size of the potential well associated with a local minimum of a continuous functional defined on a complete metric space. Applications to the homotopical stability of an isolated local minimum and to an abstract bifurcation result, as in Ioffe and Schwartzman, are described. We also establish a result on homotopical stability of arbitrary isolated critical points of continuous functionals, thus extending a result of Chang.
Journal ArticleDOI
Stability of Indices in the KKT Conditions and Metric Regularity in Convex Semi-Infinite Optimization
TL;DR: Canovas et al. as mentioned in this paper showed that ENC also entails high stability for the minimal subsets of indices involved in the KKT conditions, yielding a nice behavior not only for the optimal set mapping, but also for its inverse.
Journal ArticleDOI
Weaker conditions for subdifferential calculus of convex functions
TL;DR: In this paper, the authors established new rules for the calculus of the subdifferential mapping of the sum of two convex functions, and gave an application to derive asymptotic optimality conditions for convex optimization.
Journal ArticleDOI
Subdifferential characterization of probability functions under Gaussian distribution
TL;DR: In this paper, the authors provide subdifferential formulae of probability functions in the case of Gaussian distributions for possibly infinite-dimensional decision variables and nonsmooth (locally Lipschitzian) input data.
