Blocking sets in chain geometries

Andrea Blunck, Hans Havlicek, Corrado Zanella

In this paper we give some basic results on blocking sets on minimum size for a finite chain geometry.

Radical parallelism on projective lines and non-linear models of affine spaces

Andrea Blunck, Hans Havlicek

We introduce and investigate an equivalence relation called "radical parallelism" on the projective line over a ring. It is closely related with the Jacobson radical of the underly…

Projective lines over Jordan systems and geometry of Hermitian matrices

Andrea Blunck, Hans Havlicek

Any set of -Hermitian matrices of size over a field with involution gives rise to a projective line in the sense of ring geometry and a projective space in the…
