Paradoxical characterization of Lebesgue nonmeasurable sets

open access: yesHeliyon, 2020
We show that a set A⊆Rn is nonmeasurable in the sense of Lebesgue if and only if it has a common density point with its complement Ac. Moreover, if there exists a density point of both A and Ac, then the set of such points has a positive Lebesgue measure.

Inequalities in Riemann–Lebesgue Integrability

open access: yesMathematics, 2023
In this paper, we prove some inequalities for Riemann–Lebesgue integrable functions when the considered integration is obtained via a non-additive measure, including the reverse Hölder inequality and the reverse Minkowski inequality.

Why we need Non absolute integral in place of Lebesgue integral?

open access: yesDera Natung Government College Research Journal, 2021
In this survey note we discuss about non absolute integrable functions and we put our view about the question: Why we need Non absolute integral in place of Lebesgue integral?

Non-Newtonian Comment of Lebesgue Measure in Real Numbers

open access: yesJournal of Mathematics, 2017
We would like to generalize to non-Newtonian real numbers the usual Lebesgue measure in real numbers. For this purpose, we introduce the Lebesgue measure on open and closed sets in non-Newtonian sense and examine their basic properties.

Estimates for Parameter Littlewood-Paley gκ⁎ Functions on Nonhomogeneous Metric Measure Spaces

open access: yesJournal of Function Spaces, 2016
Let (X,d,μ) be a metric measure space which satisfies the geometrically doubling measure and the upper doubling measure conditions. In this paper, the authors prove that, under the assumption that the kernel of Mκ⁎ satisfies a certain Hörmander-type ...

On measure of noncompactness in variable exponent Lebesgue spaces and applications to integral equations

open access: yesJournal of Inequalities and Applications, 2023
A novel measure of noncompactness is defined in variable exponent Lebesgue spaces L p ( ⋅ ) $L^{p(\cdot )}$ on an unbounded domain R + $\mathbb{R}^{+}$ and its properties are examined.

Analogue of Lebesgue-Radon-Nikodym Theorem with respect to 𝑝-adic 𝑞-Measure on ℤ𝑝

open access: yesAbstract and Applied Analysis, 2011
Recently, Lebesgue-Radon-Nikodym theorem with respect to fermionic 𝑝-adic invariant measure on ℤ𝑝 was studied in Kim. In this paper we will give the analogue of the Lebesgue-Radon-Nikodym theorem with respect to 𝑝-adic 𝑞-measure on ℤ𝑝. In special case, 𝑞=
