On interval-valued $\mathbb{K}$-Riemann integral and Hermite-Hadamard type inequalities

open access: yesAIMS Mathematics, 2021
We introduce the concepts of $\mathbb{K}$-Riemann integral and radial $\mathbb{K}$-g$H$-derivative for interval-valued functions. We also give some important properties of interval-valued $\mathbb{K}$-Riemann integral, and extend interval-valued Hermite ...

On the Riemann-Stieltjes Integral [PDF]

open access: yesMathematics Interdisciplinary Research, 2022
This study contributes to the theory of Riemann-Stieltjes integral. We prove that if all continuous piecewise linear functions are Riemann-Stieltjes integrable with respect to a bounded integrator α : [a,b] → R, then α must be of bounded variation on [a ...

New Hermite-Hadamard inequalities in fuzzy-interval fractional calculus via exponentially convex fuzzy interval-valued function

open access: yesAIMS Mathematics, 2021
In the present note, we develop Hermite-Hadamard type inequality and He's inequality for exponential type convex fuzzy interval-valued functions via fuzzy Riemann-Liouville fractional integral and fuzzy He's fractional integral.

Riemann integral and its relation with Lebesgue integral

open access: yesBibechana, 2010
This review explains the limitations of the Riemann integral and focuses on the more general concept. It has been suggested that a better route is to abandon the Riemann integral for Lebesgue integral and explained the importance of Lebesgue integral in ...

On new Milne-type inequalities and applications

open access: yesJournal of Inequalities and Applications, 2023
Inequalities play a major role in pure and applied mathematics. In particular, the inequality plays an important role in the study of Rosseland’s integral for the stellar absorption.

Equivalences of Riemann Integral Based on p-Norm

open access: yesMathematics, 2018
In the usual Riemann integral setting, the Riemann norm or a mesh is adopted for Riemann sums. In this article, we use the p-norm to define the p-integral and show the equivalences between the Riemann integral and the p-integral.

Inequalities for interval-valued Riemann diamond-alpha integrals

open access: yesJournal of Inequalities and Applications, 2023
We propose the concept of Riemann diamond-alpha integrals for time scales interval-valued functions. We first give the definition and some properties of the interval Riemann diamond-alpha integral that are naturally investigated as an extension of ...

Partially Explore the Differences and Similarities between Riemann-Liouville Integral and Mellin Transform

open access: yesFractal and Fractional, 2022
At present many researchers devote themselves to studying the relationship between continuous fractal functions and their fractional integral. But little attention is paid to the relationship between Mellin transform and fractional integral.
