Hermite–Hadamard-type inequalities for interval-valued preinvex functions via Riemann–Liouville fractional integrals

open access: yesJournal of Inequalities and Applications, 2021
In this paper, we introduce ( h 1 , h 2 ) $(h_{1},h_{2})$ -preinvex interval-valued function and establish the Hermite–Hadamard inequality for preinvex interval-valued functions by using interval-valued Riemann–Liouville fractional integrals.

On the Connection between Kronecker and Hadamard Convolution Products of Matrices and Some Applications

open access: yesJournal of Inequalities and Applications, 2009
We are concerned with Kronecker and Hadamard convolution products and present some important connections between these two products. Further we establish some attractive inequalities for Hadamard convolution product.

On the Hadamard Product of Hopf Monoids [PDF]

open access: yesCanadian Journal of Mathematics, 2014
AbstractCombinatorial structures that compose and decompose give rise to Hopf monoids in Joyal's category of species. The Hadamard product of two Hopf monoids is another Hopf monoid. We prove two main results regarding freeness of Hadamard products. The first one states that if one factor is connected and the other is free as a monoid, their Hadamard ...

BVP for Hadamard Sequential Fractional Hybrid Differential Inclusions

open access: yesJournal of Function Spaces, 2022
The study is concerned with the Hadamard sequential fractional hybrid differential inclusions with two-point hybrid integral boundary conditions. With the help of the Dhage fixed-point theorem for the product of two operators and the Covitz-Nadler fixed ...

On the Hermite–Hadamard inequalities for interval-valued coordinated convex functions

open access: yesAdvances in Difference Equations, 2020
In this work, we introduce the notion of interval-valued coordinated convexity and demonstrate Hermite–Hadamard type inequalities for interval-valued convex functions on the co-ordinates in a rectangle from the plane.
