Fractional Calculus for Convex Functions in Interval-Valued Settings and Inequalities

Abstract

In this paper, we discuss the Riemann–Liouville fractional integral operator for left and right convex interval-valued functions (left and right convex I∙V-F), as well as various related notions and concepts. First, the authors used the Riemann–Liouville fractional integral to prove Hermite–Hadamard type (– type) inequality. Furthermore, – type inequalities for the product of two left and right convex I∙V-Fs have been established. Finally, for left and right convex I∙V-Fs, we found the Riemann–Liouville fractional integral Hermite–Hadamard type inequality (– Fejér type inequality). The findings of this research show that this methodology may be applied directly and is computationally simple and precise.
