e aim of this article is to obtain some new integral inclusions essentially using the interval-valued harmonically co-ordinated
convex functions and κ-Raina’s fractional double integrals. To show the validity of our theoretical results, we also give some
numerical examples.
1. Introduction
A convex analysis is the branch of mathematics in which we
study the properties of convex sets and convex functions. ese
classical concepts have a wide range of applications in both
pure and applied sciences. For instance, every one is familiar
with the role of convexity in the theory of optimization, op-
erations research, mathematical economics, theory of means
etc. In recent years the classical concepts of the convexity have
been extended and generalized in different directions using
novel and innovative ideas. For example, Dragomir [1] ex-
tended the notion of classical convex functions on the coor-
dinates and introduced the class of co-ordinated convex
functions. Iscan [2] introduced the notion of harmonically
convex functions and observed that this class enjoys some nice
properties which the convex functions have. Nikodem [3]
introduced the class of interval-valued convex functions and
discussed its properties. Zhao et al. [4] introduced the notion of
interval-valued harmonically convex functions. For more de-
tails, interested readers are referred to the book [5].
Another charming aspect of the theory of convexity is its
relation with the theory of inequalities. Many inequalities
which are known to us are direct consequences of the
applications of the convexity property of the functions. In this
regard, one of the most studied results is Hermite-Hadamard’s
inequality. is inequality provides us with a necessary and
sufficient condition for a function to be convex. It reads as,
let Θ: I [℘

is result is one of the most significant results pertaining
to the convexity property of the functions which has been
studied extensively as well as intensively. In recent years this
result has been extended and generalized in different ways using
novel and innovative ideas. For example, Dragomir [1] ob-
tained a new version of Hermite-Hdamard’s inequality by using
the co-ordinated convexity property of the functions. Iscan [2]
obtained Hermite-Hadamard’s inequality using the class of
harmonic convex functions. Zhao obtained a similar result by
using the interval-valued harmonically convex functions.
Sarikaya et al. [6] have utilized the concepts of fractional
calculus and obtained fractional analogues of Hermite-Hada-
mard’s inequality. For some more recent studies regarding
Hermite-Hadamard’s inequality and its applications, see [7].
