A generalisation of bent vectors for Butson Hadamard matrices

José Andrés Armario, Ronan Egan, Hadi Kharaghani +1

An $n \times n$ complex matrix $M$ with entries in the $k^{th}$ roots of unity which satisfies $M M^{*} = n I_{n}$ is called a Butson Hadamard matrix. While a matrix with…

Centraliser algebras of monomial representations and applications in combinatorics

Santiago Barrera Acevedo, Padraig Ó Catháin, Heiko Dietrich +1

Centraliser algebras of monomial representations of finite groups may be constructed and studied using methods similar to those employed in the study of permutation groups. Guided…
