Maximal arcs and extended cyclic codes
Stefaan De Winter, Cunsheng Ding, Vladimir D. Tonchev
It is proved that for every such that divides , where is a power of 2, there exists a Denniston maximal arc of degree in $\PG(2,q)$, being invariant…

Non-existence of partial difference sets of order 8p^3 in Abelian groups
Stefaan De Winter, Zeying Wang
In this paper we prove non-existence of nontrivial partial difference sets in Abelian groups of order 8p^3, where p \geq 3 is a prime number.

Non-existence of two types of partial difference sets
Stefaan De Winter, Eric Neibert, Zeying Wang
In this note we prove the non-existence of two types of partial difference sets in Abelian groups of order 216. This finalizes the classification of parameters for which a partial…
