Aims and Scope

The concern of this international mathematical journal is to disseminate theoretical knowledge in the field of Convex Analysis and, at the same time, cultivate and extend its applications. In this sense it publishes research articles touching the areas of Calculus of Variations, Control Theory, Measure Theory, Functional Analysis, Differential Equations, Integral Equations, Optimization and Mathematical Programming. Of particular interest are topics related to nonsmooth analysis, generalized differentiability, and set-valued functions.
