Homomorphisms of matrix algebras and constructions of Butson-Hadamard matrices

Padraig O Cathain, Eric Swartz

An $n \times n$ matrix $H$ is Butson-Hadamard if its entries are $k^{th}$ roots of unity and it satisfies $H H^{*} = n I_{n}$ . Write $B H (n, k)$ for the set of such matrices. Suppo…

A classification of finite locally 2-transitive generalized quadrangles

John Bamberg, Cai Heng Li, Eric Swartz

Ostrom and Wagner (1959) proved that if the automorphism group $G$ of a finite projective plane $π$ acts $2$ -transitively on the points of $π$ , then $π$ is isomorphic to the Desarg…
