Integral Operator Defined by k-th Hadamard Product

Journal of Mathematical and Fundamental Sciences, 2013
We introduce an integral operator on the class A of analytic functions in the unit disk involving k Æ’{ th Hadamard product (convolution) corresponding to the differential operator defined recently by Al-Shaqsi and Darus.

The Application of Generalized Quasi-Hadamard Products of Certain Subclasses of Analytic Functions with Negative and Missing Coefficients

Mathematics, 2019
In this paper, we introduce a new generalized differential operator using a new generalized quasi-Hadamard product, and certain new classes of analytic functions using subordination.

Determinantal inequalities for block Hadamard product and Khatri-Rao product of positive definite matrices

AIMS Mathematics, 2022
In this paper, we first give an alternative proof for a result of Liu et al. in [Math. Inequal. Appl. 20 (2017) 537–542]. Then we present two inequalities for the block Hadamard product and the Khatri-Rao product respectively.

Geometric means and Hadamard products [PDF]

Mathematical Inequalities & Applications, 2005
The authors generalize the geometric mean for positive definite matrices defined by \textit{W. Pusz} and \textit{S. L. Woronowicz} [Rep. Math. Phys. 8, 159--170 (1975; Zbl 0327.46032)] to any number of matrices, obtaining an interesting inequality between Hadamard products of such means and the Hadamard product of original matrices.

Hadamard Product Arguments and Their Applications

IEEE Access
The 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,

Bulk behaviour of Schur-Hadamard products of symmetric random matrices [PDF]

, 2014
We develop a general method for establishing the existence of the Limiting Spectral Distributions (LSD) of Schur-Hadamard products of independent symmetric patterned random matrices.

Hadamard Products of Product Operators and the Design of Gradient-Diffusion Experiments for Simulating Decoherence by NMR Spectroscopy

, 2000
An extension of the product operator formalism of NMR is introduced, which uses the Hadamard matrix product to describe many simple spin 1/2 relaxation processes. The utility of this formalism is illustrated by deriving NMR gradient-diffusion experiments

Fractional Hadamard powers of symmetric positive-definite matrices [PDF]

, 2000
Let A = (aij) andB = (bij) be matrices of the same size. Then their Hadamard product (also called Schur product) A B is dened by entrywise multiplication: A B = (aij bij) . The Hadamard unit matrix is the matrix U all of whose entries are 1 (the size

Continuity of symplectically adjoint maps and the algebraic structure of Hadamard vacuum representations for quantum fields on curved spacetime

, 1996
We derive for a pair of operators on a symplectic space which are adjoints of each other with respect to the symplectic form (that is, they are sympletically adjoint) that, if they are bounded for some scalar product on the symplectic space dominating ...
