Counting results for thin Butson matrices
Teo Banica
A partial Butson matrix is a matrix having its rows pairwise orthogonal, where is the group of -th roots o…
Quantum invariants of deformed Fourier matrices
Teo Banica, Julien Bichon
We study the deformed tensor products of complex Hadamard matrices, . One problem is that of reconstructing the quantum group ou…
The quantum algebra of partial Hadamard matrices
Teo Banica, Adam Skalski
A partial Hadamard matrix is a matrix whose rows are pairwise orthogonal. We associate to each such a certain quantum semigroup of quantum p…
The Gale-Berlekamp game for complex Hadamard matrices
Teodor Banica
Associated to a complex Hadamard matrix is the complex probability measure describing the distribution of , where $…
Regularity questions for complex Hadamard matrices
Teodor Banica, Lorenzo Pittau
We study the partial Hadamard matrices which are regular, in the sense that the scalar products between pairs of distinct rows decompose as sums of…
The Gale-Berlekamp game for Hadamard matrices
Teodor Banica
Given an Hadamard matrix we consider the function given by , which sums the entries…
