On Formulae for the Ioffe Geometric Subdifferential of a Supremum Function

Pedro Pérez-Aros; David Salas; Emilio Vilches

Abstract

We study the first order variational behavior of the supremum of an arbitrary family of lower semicontinuous functions over a weakly compactly generated β-smooth Banach space. In this context, we present new upper-estimations for the viscosity subdifferential and the Ioffe geometric subdifferential.
