A characterization of complex Hadamard matrices appearing in families of MUB triplets
Ákos K. Matszangosz, Ferenc Szöllősi
It is shown that a normalized complex Hadamard matrix of order having three distinct columns, each containing at least one entry necessarily belongs to the transposed Four…
A note on five dimensional kissing arrangements
Ferenc Szöllősi
The kissing number is the maximum number of pairwise non-overlapping unit spheres each touching a central unit sphere in the -dimensional Euclidean space. In this note we…
A note on the existence of BH(19,6) matrices
Ferenc Szöllősi
In this note we utilize a non-trivial block approach due to M. Petrescu to exhibit a Butson-type complex Hadamard matrix of order 19, composed of sixth roots of unity.
The quaternary complex Hadamard matrices of orders 10, 12, and 14
Pekka H. J. Lampio, Ferenc Szöllősi, Patric R. J. Östergård
A complete classification of quaternary complex Hadamard matrices of orders 10, 12 and 14 is given, and a new parametrization scheme for obtaining new examples of affine parametric…
