Inequalities of Hermite-Hadamard Type for K-Bounded Modulus Convex Complex Functions

Authors: Silvestru Sever Dragomir

Abstract

Let $D\subset \mathbb{C}$ be a convex domain of complex numbers and $K>0.$ We say that the function $f:D\subset \mathbb{C\rightarrow C}$ is called $K$% -bounded modulus convex, for the given $K>0,$ if it satisfies the condition% \begin{equation*} \left\vert \left( 1-\lambda \right) f\left( x\right) +\lambda f\left( y\right) -f\left( \left( 1-\lambda \right) x+\lambda y\right) \right\vert \leq \frac{1}{2}K\lambda \left( 1-\lambda \right) \left\vert x-y\right\vert ^{2} \end{equation*}% for any $x,$ $y\in D$ and $\lambda \in \left[ 0,1\right] .$ In this paper we establish some new Hermite-Hadamard type inequalities for the complex integral on $\gamma ,$ a smooth path from $\mathbb{C}$, and $K$% -bounded modulus convex functions. Some examples for integrals on segments and circular paths are also given.
