The Smith group of the hypercube

David Chandler, Peter Sin, Qing Xiang

The $n$ -cube graph is the graph on the vertex set of $n$ -tuples of $0$ s and $1$ s, with two vertices joined by an edge if and only if the $n$ -tuples differ in exactly one component.…

The Smith and critical groups of Paley graphs

David Chandler, Peter Sin, Qing Xiang

There is a Paley graph for each prime power $q$ such that $q \equiv 1 (mod 4)$ . The vertex set is the field $F q$ and two vertices $x$ and $y$ are joined by an edge if and onl…

The sizes of the intersection of two unitals in PG $(2, q^{2})$

David B. Chandler

We show that the size of the intersection of a Hermitian variety in $\PG(n,q^2)$, and any set satisfying an $r$ -dimensional-subspace intersection property, is congruent to 1 modulo…

Permutation Polynomials of Degree 6 or 7 over Finite Fields of Characteristic 2

Jiyou Li, David B. Chandler, Qing Xiang

In \cite{D1}, Dickson listed all permutation polynomials up to degree 5 over an arbitrary finite field, and all permutation polynomials of degree 6 over finite fields of odd charac…

Incidence Modules for Symplectic Spaces in Characteristic Two

David B. Chandler, Peter Sin, Qing Xiang

We study the permutation action of a finite symplectic group of characteristic 2 on the set of subspaces of its standard module which are either totally isotropic or else complemen…
