A Hadamard product involving inverse-positive matrices
Special Matrices, 2015 In this paperwe study the Hadamard product of inverse-positive matrices.We observe that this class of matrices is not closed under the Hadamard product, but we show that for a particular sign pattern of the inverse-positive matrices A and B, the Hadamard

On Hadamard products of linear varieties [PDF]
Journal of Algebra and Its Applications, 2016 In this paper, we address the Hadamard product of linear varieties not necessarily in general position. In [Formula: see text], we obtain a complete description of the possible outcomes. In particular, in the case of two disjoint finite sets [Formula: see text] and [Formula: see text] of collinear points, we get conditions for [Formula: see text] to ...

Journal 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.

Journal 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.

Hermite–Hadamard type inequalities for multiplicatively harmonic convex functions
Journal of Inequalities and Applications, 2023 In this work, the notion of a multiplicative harmonic convex function is examined, and Hermite–Hadamard inequalities for this class of functions are established.

On the Hadamard Product of Hopf Monoids [PDF]
Canadian 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
Journal 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 ...
