Deformed Fourier matrices in bistochastic form

Combinatorics 2019-11-14 v3

Abstract

Many interesting examples of complex Hadamard matrices HMN(C)H\in M_N(\mathbb C) can be put, up to the standard equivalence relation for such matrices, in bistochastic form. We discuss here this phenomenon, with a number of computations for some of the most basic such matrices, namely the deformations of the Fourier matrix FNMN(C)F_N\in M_N(\mathbb C).
