Constructing, Classifying and Studying the Space of Small Integer Weighing Matrices

Assaf Goldberger, Radel Ben-Av, Giora Dula +1

Integer weighing matrices (IW-matrices for short) are integer valued orthogonal square matrices. One usecase of these is to create classical weighing matrices with various block st…

An algorithm for constructing and classifying the space of small integer weighing matrices

Radel Ben-Av, Giora Dula, Assaf Goldberger +1

In this paper we describe an algorithm for generating all the possible $P I W (m, n, k)$ - integer $m \times n$ Weighing matrices of weight $k$ up to Hadamard equivalence. Our method is…

Energy Minimization in $C P^{n}$ : Some Numerical and Analytical Results

Radel Ben Av, Assaf Goldberger, Giora Dula +1

We study the problem of minimizing the energy function $M^{p} (m, n) := min \sum_{1 \leq i < j \leq m} ∣ ⟨ v_{i}, v_{j} ⟩ ∣^{p}$ , where $v_{i}$ are unit vectors in $F^{n}$ , $F = R$ or…
