On Subgradients of Convex Functions and Orlicz Pseudo-Norms for Vector-Valued Functions

Functional Analysis 2026-04-15 v3

Abstract

We discuss variants of construction of measurable subgradients for multivariate convex functions and the problem of characterization of the Δ2\Delta_2-condition in terms of their directional derivatives. Furthermore we study related basic properties of Luxemburg and Orlicz pseudo-norms for vector-valued functions.
