Multidimensional Hadamard composition
Siberian Mathematical Journal, 1994The generalization of the classical Hadamard theorem of multiplication of singularities onto multidimensional complex situation is connected with the construction of the Hadamard composition in \(\mathbb{C}^n\). Thus, the realization of analog of the Hadamard composition by use of the Szegö kernel of an arbitrary \(n\)-circular domain in \(\mathbb{C}^n\

Multidimensional Hadamard composition and sums with linear constraints on the summation indices
Siberian Mathematical Journal, 1989Let D be an (m\(\times n)\)-dimensional matrix with integer entries and let \(\mu \in {\mathbb{Z}}^ n\). Given two power series \(f(\xi)=\sum a(\alpha)\xi^{\alpha}\), \((\xi \in {\mathbb{C}}^ n\), \(\alpha \in ({\mathbb{Z}}_+)^ n)\) and \(g(\eta)=\sum b(\beta)\eta^{\beta}\) \((\eta \in {\mathbb{C}}^ m\), \(\beta \in ({\mathbb{Z}}_+)^ m)\) the author ...

Hadamard matrices of composite orders
2022Summary: In this paper, we give a method for the constructions of Hadamard matrices of composite orders by using suitable \(T\)-matrices and known Hadamard matrices. We establish a formula for \(T\)-matrices and Hadamard matrices and discuss under what condition we can get \(T\)-matrices from the known Hadamard matrices.

On Hadamard Compositions of Gelfond–Leontiev Derivatives of Analytic Functions
Russian Mathematics, 2020For analytic functions f and g, the growth of the Hadamard composition of their Gelfond-Leont'ev derivatives is investigated in terms of generalized orders. A relation between the behaviors of the maximal terms of the Hadamard composition of Gelfond-Leont'ev derivatives and those of the Gelfond-Leont'ev derivative of a Hadamard composition is ...

HADAMARD COMPOSITION OF SERIES IN SYSTEMS OF FUNCTIONS
Bukovinian Mathematical Journal, 2023For regularly converging in ${\Bbb C}$ series $A_j(z)=\sum\limits_{n=1}^{\infty}a_{n,j}f(\lambda_nz)$, $1\le j\le p$, where $f$ is an entire transcendental function, the asymptotic behavior of a Hadamard composition $A(z)=\break=(A_1*...*A_p)_m(z)=\sum\limits_{n=1}^{\infty} \left(\sum\limits_{k_1+\dots+k_p=m}c_{k_1...k_p}a_{n,1}^{k_1}\cdot...\cdot a_{n,

Hermite-Hadamard type inequalities for composite m-convex functions
AIP Conference Proceedings, 2021The Hermite-Hadamard type inequality has been extended to some classes of convex functions and composite convex functions. In this paper, we refine the definition of composite-ɸ−1 convex function and definition of m-convex function to define the composite-ɸ−1 m-convex functions. From the definition, we obtain some inequalities related to GA-m-convexity,

The Superconvergence of the Composite Trapezoidal Rule for Hadamard Finite Part Integrals
Numerische Mathematik, 2005Several papers have dealt with quadrature formulas for evaluating Hadamard finite part integrals (or hypersingular integrals) with \((p+1)\)-order singularity. On the other hand the composite trapezoidal method has been applied for numerical integration and numerical solution of integral equations with smooth or weakly singular kernels. The paper deals

Composite complex Hadamard spectra of Boolean functions
1996 IEEE International Symposium on Circuits and Systems (ISCAS), 1996A new class of orthogonal transform, Complex Hadamard Transform is proposed as a spectral technique for analysis, synthesis and testing of Boolean functions. The method is presented to evaluate Complex Hadamard Spectra of AND, OR and XOR of Boolean functions directly front the spectra of the separate Boolean functions.
