On Generalized Hadamard Matrices and Difference Matrices:
Bradley W. Brock, Robert Compton, Warwick de Launey +1
We give some very interesting matrices which are orthogonal over groups and, as far as we know, referenced, but in fact undocumented. This note is not intended to be published but…
On the Density of the Set of Known Hadamard Orders
Warwick de Launey, Daniel M. Gordon
Let be the number of for which a Hadamard matrix of order exists. Hadamard's conjecture states that is about . From Paley's constructions of Hadam…
A Fourier-analytic Approach to Counting Partial Hadamard Matrices
Warwick de Launey, David A. Levin
In this paper, we study a family of lattice walks which are related to the Hadamard conjecture. There is a bijection between paths of these walks which originate and terminate at t…
On the Asymptotic Existence of Hadamard Matrices
Warwick de Launey
It is conjectured that Hadamard matrices exist for all orders (). However, despite a sustained effort over more than five decades, the strongest overall existence results…
