On the generalized Hadamard product and the Jordan-Hadamard product [PDF]

Bulletin of the Australian Mathematical Society, 1980
The generalized Hadamard product S * T and the Jordan-Hadamard product S ∘ T of two operator-matrices S and T are introduced. They coincide with the usual Hadamard product of two complex matrices when the underlying Hilbert spaces are one-dimensional. Some inequalities which hold true for the usual Hadamard product of positive definite complex matrices

Holomorphic Cohomological Convolution and Hadamard Product [PDF]

Publications of the Research Institute for Mathematical Sciences, 2022
In this article we explain the link between Pohlen’s extended Hadamard product and the holomorphic cohomological convolution on \mathbb{C}^* . For this purpose we introduce a generalized Hadamard product, which is defined even if the holomorphic ...

Hybrid kernels integrating genomic and multispectral data improve wheat genomic prediction accuracy. [PDF]

Plant Genome
Abstract Genomic selection (GS) is transforming plant breeding by enabling more accurate and efficient identification of superior genotypes. However, its practical implementation remains challenging, as achieving high prediction accuracy is critical for its success. Several factors—including sample size, the degree of relatedness among individuals, and

Hadamard products in F(p,q,s) spaces

Journal of Function Spaces and Applications, 2010
We characterize coefficient multipliers from X to F(p, q, s), 0 < s < ∞, where X is either the Hardy space H1 or F(p, q, s).

Frequency-difference sparse Bayesian learning for unambiguous direction-of-arrival estimation [PDF]

JASA Express Letters
The frequency-difference (FD) method uses the FD Hadamard product, comprising auto-products to model below-band acoustic fields and unintended cross-products, for efficient direction-of-arrival (DOA) estimation under spatial aliasing.

Construction of Sylvester-Hadamard Matrices by Using Binary Code [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2009
A simple method is presented which defines Sylvester-Hadamard matrices in terms of products of binary code. This method is based representation of natural number as binary code which take only two value 0 or 1.
