Title: Fenchel's Duality Theorem for Nearly Convex Functions.
Authors: Boţ, R. I.1 bot@mathematik.tu-chemnitz.de, Grad, S. M.1, Wanka, G.1

Subjects: Duality theory (Mathematics), Algebra, Mathematical analysis, Convex domains, Convex functions, Real variables, Hypothesis, Function spaces, Fenchel-Orlicz spaces
Abstract: We present an extension of Fenchel's duality theorem by weakening the convexity assumptions to near convexity. These weak hypotheses are automatically fulfilled in the convex case. Moreover, we show by a counterexample that a further extension to closely convex functions is not possible under these hypotheses. [ABSTRACT FROM AUTHOR]
