Results on partial geometries with an abelian Singer group of rigid type
Stefaan De Winter, Ellen Kamischke, Eric Neubert +1
A partial geometry admitting an abelian Singer group is called of rigid type if all lines of have a trivial stabilizer in . In this paper, we show that if a partial…

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…
