Proofs of two conjectures on ternary weakly regular bent functions
Tor Helleseth, Henk D. L. Hollmann, Alexander Kholosha +2
We study ternary monomial functions of the form $f(x)=\Tr_n(ax^d)$, where $x\in \Ff_{3^n}$ and $\Tr_n: \Ff_{3^n}\to \Ff_3$ is the absolute trace function. Using a lemma of Hou \cit…
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…
Semi-regular Relative Difference Sets with Large Forbidden Subgroups
Tao Feng, Qing Xiang
Motivated by a connection between semi-regular relative difference sets and mutually unbiased bases, we study relative difference sets with parameters in groups of no…
Association schemes from the action of fixing a nonsingular conic in PG(2,q)
Henk D. L. Hollmann, Qing Xiang
The group has an embedding into such that it acts as the group fixing a nonsingular conic in . This action affords a coherent configuration on…
Symmetric Bush-type Hadamard matrices of order exist for all odd
Mikhail Muzychuk, Qing Xiang
Using reversible Hadamard difference sets, we construct symmetric Bush-type Hadamard matrices of order for all odd integer .
Amorphic association schemes with negative Latin square type graphs
James A. Davis, Qing Xiang
Applying results from partial difference sets, quadratic forms, and recent results of Brouwer and Van Dam, we construct the first known amorphic association scheme with negative La…
