Research output: Contribution to journalArticle


The concept of generalized convex functions introduced by Beckenbach [E.F. Beckenbach, Generalized convex functions, Bull. Amer. Math. Soc. 43 (1937) 363-371] is extended to the two-dimensional case. Using three-parameter families, we define generalized convex (midconvex, M-convex) functions f : D ⊆ R2 → R and show some continuity properties of them.
