Double neutrosophic integrals [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
Several previous papers dealt with neutrosophic integrals without introducing the idea of double neutrosophic integrals. In this article, double integrals were discussed by presenting several theories in double neutrosophic integrals over a rectangle and

An Expository Lecture of María Jesús Chasco on Some Applications of Fubini’s Theorem

open access: yesAxioms, 2021
The usefulness of Fubini’s theorem as a measurement instrument is clearly understood from its multiple applications in Analysis, Convex Geometry, Statistics or Number Theory. This article is an expository paper based on a master class given by the second

Hermite–Hadamard-Type Inequalities for Coordinated Convex Functions Using Fuzzy Integrals

open access: yesMathematics, 2023
In this paper, some estimates of third and fourth inequalities in Hermite–Hadamard-type inequalities for coordinated convex functions are proved using the non-additivity of the integrals and Fubini’s theorem for fuzzy integrals.

The Fubini Theorem for Normal Lie Subgroups of Index 2n

open access: yesRCT: Revista de Ciência e Tecnologia, 2023
In this paper we present a new proof to generalize the Fubini's Theorem for the even index subgroup of a compact Lie group, using a recent result on the semi-direct product of groups.

Some reverse inequalities of Hardy type on time scales

open access: yesAdvances in Difference Equations, 2020
In this article, we obtain some new dynamic inequalities of Hardy type on time scales. The main results are derived using Fubini’s theorem and the chain rule on time scales.

On Some Generalizations of Reverse Dynamic Hardy Type Inequalities on Time Scales

open access: yesAxioms, 2022
In the present paper, we prove some new reverse type dynamic inequalities on T. Our main inequalities are proved by using the chain rule and Fubini’s theorem on time scales T. Our results extend some existing results in the literature.

Time-Scale Integral Inequalities of Copson with Steklov Operator in High Dimension

open access: yesJournal of Mathematics, 2022
The paper derives some new time-scale (TS) dynamic inequalities for multiple integrals. The obtained inequalities are special cases of Copson integral using Steklov operator in (TS) version with high dimension.

Fubini's theorem in codimension two [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2009
We classify codimension two analytic submanifolds X of projective space having the property that any line through a general point p having contact to order two with X at p automatically has contact to order three. We give applications to the study of the Debarre--de Jong conjecture, and of n-dimensional varieties whose Fano variety of lines has ...

On nabla conformable fractional Hardy-type inequalities on arbitrary time scales

open access: yesJournal of Inequalities and Applications, 2021
The main aim of the present article is to introduce some new ∇-conformable dynamic inequalities of Hardy type on time scales. We present and prove several results using chain rule and Fubini’s theorem on time scales.
