The Minimal Robust Core of Abstract Subdifferentials
M. D. Voisei
This paper introduces the metric-dependent core subdifferential, a local robust affine-support construction for extended-real functions on metrizable topological vector spaces. A c…

Monotone extensions into compact target sets in dual systems
M. D. Voisei
We study monotone extension problems in the general framework of dual systems, without assuming separation. The paper develops a compact target-set formulation that includes multiv…

General monotonicity
M. D. Voisei
This article employs techniques from convex analysis to present characterizations of (maximal) monotonicity, similar to the well-established characterizations of (maximal) mono…
