Association schemes from the action of $P G L (2, q)$ fixing a nonsingular conic in PG(2,q)

Henk D. L. Hollmann, Qing Xiang

The group $P G L (2, q)$ has an embedding into $P G L (3, q)$ such that it acts as the group fixing a nonsingular conic in $P G (2, q)$ . This action affords a coherent configuration $R (q)$ on…

Pseudocyclic association schemes arising from the actions of PGL(2,2^m) and PΓL(2,2^m)

Henk D. L. Hollmann, Qing Xiang

The action of $P G L (2, 2^{m})$ on the set of exterior lines to a nonsingular conic in $P G (2, 2^{m})$ affords an association scheme, which was shown to be pseudocyclic in Hollmann's thesis…

A Class of Permutation Polynomials of $\bF_{2^m}$ Related to Dickson Polynomials

Henk D. L. Hollmann, Qing Xiang

We construct a class of permutation polynomials of $\bF_{2^m}$ that are closely related to Dickson polynomials.
