Hadamard Product of Monomial Ideals and the Hadamard Package
MathematicsIn this paper, we generalize and study the concept of Hadamard product of ideals of projective varieties to the case of monomial ideals. We have a research direction similar to the one of the join of monomial ideals contained in a paper of Sturmfels and ...

The closure property of H $\mathcal{H}$ -tensors under the Hadamard product [PDF]
Journal of Inequalities and Applications, 2017 In this paper, we investigate the closure property of H $\mathcal {H}$ -tensors under the Hadamard product. It is shown that the Hadamard products of Hadamard powers of strong H $\mathcal{H}$ -tensors are still strong H $\mathcal{H}$ -tensors.

A Hadamard product involving inverse-positive matrices [PDF]
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 the Hadamard product of degenerate subvarieties [PDF]
Portugaliae Mathematica, 2020 We consider generic degenerate subvarieties X_i \subset \mathbb P^n . We determine an integer N , depending on the varieties, and for

A novel matrix multiplication framework for modeling genotype-by-environment interaction in genomic prediction [PDF]
Frontiers in GeneticsAccurate modeling of genotype-by-environment (G × E) interaction is a central challenge in plant breeding, as it determines how genetic potential is expressed across heterogeneous and changing environments.

Hadamard Product Arguments and Their Applications
IEEE AccessThe Hadamard product (also known as element-wise multiplication) is a fundamental operation in linear algebra, performed by multiplying corresponding elements of two matrices with the same dimensions. This operation plays a crucial role in various fields,

On Hadamard Product of Hypercomplex Numbers [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 Certain product rules take various forms in the set of hypercomplex numbers. In this paper, we introduce a new multiplication form of the hypercomplex numbers that will be called «the Hadamard product», inspired by the analogous product in the real ...

On the Hadamard product of inverse M-matrices
Linear Algebra and its Applications, 2000 I. Schur has shown that the class of positive semidefinite \(n \times n\) matrices is closed under Hadamard multiplication. It is shown that the same holds for the class of inverse \(M\)-matrices if and only if \(n\) is less than 4. Further results concern \textit{R. A. Willoughby}'s inverse \(M\)-matrices [ibid.

On the Hermite-Hadamard Inequality and Other Integral Inequalities Involving Two Functions [PDF]
, 2009 We establish some new Hermite-Hadamard-type inequalities involving product of two functions. Other integral inequalities for two functions are obtained as well.
