Boys-and-girls Birthdays and Hadamard Products [PDF]
Fundamenta Informaticae, 2012 Boltzmann models from statistical physics, combined with methods from analytic combinatorics, give rise to efficient and easy-to-write algorithms for the random generation of combinatorial objects.

Advances in Difference Equations, 2021 In this paper, we establish some Hermite–Hadamard–Fejér type inclusions for the product of two co-ordinated convex interval-valued functions. These inclusions are generalizations of some results given in earlier works.

On Hadamard and Kronecker products in covariance structures for genotype × environment interaction
The Plant Genome, 2020 When including genotype × environment interactions (G × E) in genomic prediction models, Hadamard or Kronecker products have been used to model the covariance structure of interactions.

On the hadamard products of Schlicht functions and applications [PDF]
International Journal of Mathematics and Mathematical Sciences, 1985 We show that each of the schlicht classes of starlike, convex, close-to-convex and strongly starlike with respect to symmetric points is invariant under the Hadamard product with the class of convex functions.

A Tensor Space for Multi-View and Multitask Learning Based on Einstein and Hadamard Products: A Case Study on Vehicle Traffic Surveillance Systems [PDF]
SensorsSince multi-view learning leverages complementary information from multiple feature sets to improve model performance, a tensor-based data fusion layer for neural networks, called Multi-View Data Tensor Fusion (MV-DTF), is used. It fuses M feature spaces

Singularity analysis, Hadamard products, and tree recurrences [PDF]
, 2003 We present a toolbox for extracting asymptotic information on the coefficients of combinatorial generating functions. This toolbox notably includes a treatment of the effect of Hadamard products on singularities in the context of the complex Tauberian ...

Block-matrix generalizations of Schur's basic theorems on Hadamard products [PDF]
, 1992 In a classic 1911 paper, I. Schur gave several useful bounds for the spectral norm and eigenvalues of the Hadamard (entrywise) product of two matrices.

Scalable Evaluation of Hadamard Products with Tensor Product Basis for Entropy-Stable High-Order Methods [PDF]
Journal of Computational Physics, 2023 A sum-factorization form for the evaluation of Hadamard products with a tensor product basis is derived in this work. The proposed algorithm allows for Hadamard products to be computed in $\mathcal{O}\left(n^{d+1}\right)$ flops rather than $\mathcal{O ...

A sharper multivariate Christol's theorem with applications to diagonals and Hadamard products [PDF]
arXiv.org, 2023 We provide a new proof of the multivariate version of Christol's theorem about algebraic power series with coefficients in finite fields, as well as of its extension to perfect ground fields of positive characteristic obtained independently by Denef and ...

Hadamard Products of Stable Polynomials Are Stable [PDF]
Journal of Mathematical Analysis and Applications, 1996 A real polynomial is said to be (Hurwitz or asymptotically) stable if all its zeros lie in the open left half of the complex plane. The authors show that the Hadamard coefficientwise product of two stable polynomials is again stable, improving upon some known results.
