The projective plane is a stabilizer
We prove that every 3-connected GF(q)-representable matroid that contains the projective plane, PG(2, q), as a minor is uniquely representable.

On the isotopism classes of finite semifields
A projective plane is called a translation plane if there exists a line L such that the group of elations with axis L acts transitively on the points not on L. A translation plane...

Enumeration of orthogonal Buekenhout unitals
In this paper we develop general techniques for enumerating orthogonal Buekenhout unitals embedded in two-dimensional translation planes. We then apply these techniques in the reg...

Minimal non-orientable matroids in a projective plane
: We construct a new family of minimal non-orientable matroids of rank three. Some of these matroids embed in Desarguesian projective planes. This answers a question of Ziegler: fo...
