Real and complex functions form the backbone of modern mathematical analysis, uniting the study of continuity, differentiability, and integrability on the real line with the rich structure of analytic ...

Abstract. In this paper, we first investigate abstract convexity of non-negative increasing and radiant (IR) functions over a topological vector space X. We also characterize the essential results of ...
