On approximately $t$-convex functions

Publicationes Mathematicae Debrecen, 2005
Let \(\varepsilon =(\varepsilon _{o},\dots,\varepsilon _{k})\in [ 0,\infty [ ^{k+1}, p=(p_{o},\dots,p_{k})\in [ 0,1[^{k+1}\) and \(t\in ]0,1[\) be fixed parameters. A real valued function \(f\) defined on an open convex set \(D\) is called \((\varepsilon ,p,t)-\) convex if it satisfies \[ f(tx+(1-t)y)\leq tf(x)+(1-t)f(y)+\sum_{i=0}^{k}\varepsilon _{i ...

On Korenblum convex functions

Commentationes Mathematicae, 2017
Summary: We introduce a new class of generalized convex functions called the \(\kappa\)-convex functions, based on Korenblum's concept of \(\kappa\)-decreasing functions, where \(\kappa\) is an entropy (distortion) function. We study continuity and differentiability properties of these functions, and we discuss a special subclass which is a counterpart

On Convex Univalent Functions

Canadian Journal of Mathematics, 1970
In what follows, we suppose that ƒ(z) = Σ0∞anzn is regular for |z| < 1. LetandThen (see, for example, [6, pp. 235-236]), for 0 ≦ r < ρ < 1, we have:The following results are well known.
