Hadamard Products of Symbolic Powers and Hadamard Fat Grids [PDF]
Mediterranean Journal of Mathematics, 2022 In this paper we address the question if, for points $$P, Q \in \mathbb {P}^{2}$$ P , Q ∈ P 2 , $$I(P)^{m} \star I(Q)^{n}=I(P \star Q)^{m+n-1}$$ I ( P ) m ⋆ I ( Q ) n = I ( P ⋆ Q ) m + n - 1 and we obtain different results according to the number of zero

Hadamard products of hypersurfaces [PDF]
Journal of Pure and Applied Algebra, 2021 . In this paper we characterize hypersurfaces for which their Hadamard product is still a hypersurface Then we study hypersurfaces and, more gener- ally, varieties which are indempotent under Hadamard powers.

Hadamard products and BPS networks [PDF]
Journal of High Energy Physics, 2023 We study examples of fourth-order Picard-Fuchs operators that are Hadamard products of two second-order Picard-Fuchs operators. Each second-order Picard-Fuchs operator is associated with a family of elliptic curves, and the Hadamard product computes ...

Hadamard products and binomial ideals [PDF]
Journal of Pure and Applied Algebra, 2022 We study the Hadamard product of two varieties $V$ and $W$, with particular attention to the situation when one or both of $V$ and $W$ is a binomial variety.

Hadamard products and multivariate statistical analysis [PDF]
Linear Algebra and Its Applications, 1973 The Hadamard product of two matrices multiplied together elementwise is a rather neglected concept in matrix theory and has found only brief and scattered application in statistical analysis.

On the Connection between Kronecker and Hadamard Convolution Products of Matrices and Some Applications [PDF]
Journal of Inequalities and Applications, 2009 We are concerned with Kronecker and Hadamard convolution products and present some important connections between these two products. Further we establish some attractive inequalities for Hadamard convolution product.

On Hadamard products of linear varieties [PDF]
Journal of Algebra and Its Applications, 2016 In this paper we address the Hadamard product of linear varieties not necessarily in general position. In $\mathbb{P}^2$ we obtain a complete description of the possible outcomes.

Recompression of Hadamard Products of Tensors in Tucker Format
SIAM Journal of Scientific Computing, 2017 The Hadamard product features prominently in tensor-based algorithms in scientific computing and data analysis. Due to its tendency to significantly increase ranks, the Hadamard product can represent a major computational obstacle in algorithms based on ...
