Some new Riemann-Liouville fractional integral inequalities for interval-valued mappings

Abstract

<abstract> <p>The notions of convex mappings and inequalities, which form a strong link and are key parts of classical analysis, have gotten a lot of attention recently. As a familiar extension of the classical one, interval-valued analysis is frequently used in the research of control theory, mathematical economy and so on. Motivated by the importance of convexity and inequality, our aim is to consider a new class of convex interval-valued mappings (<italic>I-V⋅Ms</italic>) known as left and right (<italic>L-R</italic>) $ \mathfrak{J} $-convex interval-valued mappings through pseudo-order relation ($ {\le }_{p} $) or partial order relation, because in interval space, both concepts coincide, so this order relation is defined in interval space. By using this concept, first we obtain Hermite-Hadamard (<italic>HH</italic>-) and Hermite-Hadamard-Fejér (<italic>HH</italic>-Fejér) type inequalities through pseudo-order relations via the Riemann-Liouville fractional integral operator. Moreover, we have shown that our results include a wide class of new and known inequalities for <italic>L-R</italic> $ \mathfrak{J} $-convex- <italic>I-V⋅Ms</italic> and their variant forms as special cases. Under some mild restrictions, we have proved that the inclusion relation "$ \subseteq $" is coincident to pseudo-order relation "$ {\le }_{p} $" when the <italic>I-V⋅M</italic> is <italic>L-R</italic> $ \mathfrak{J} $-convex or <italic>L-R</italic> $ \mathfrak{J} $-concave. Results obtained in this paper can be viewed as an improvement and refinement of classical known results.</p> </abstract>
