Geometry of the inversion in a finite field and partitions of in normal rational curves
Michel Lavrauw, Corrado Zanella
Let be a finite field and let be a subfield of . Consider as a vector space over and the associated projective space that is isomorph…
Incidence and Combinatorial Properties of Linear Complexes
Hans Havlicek, Corrado Zanella
In this paper a generalisation of the notion of polarity is exhibited which allows to completely describe, in an incidence-geometric way, the linear complexes of -subspaces. A g…
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.
Divisible designs from twisted dual numbers
Andrea Blunck, Hans Havlicek, Corrado Zanella
The generalized chain geometry over the local ring of twisted dual numbers, where is a finite field, is interpreted as a divisible design obtained from an imprimitive…
Lifting of divisible designs
Andrea Blunck, Hans Havlicek, Corrado Zanella
The aim of this paper is to present a construction of -divisible designs for , because such divisible designs seem to be missing in the literature. To this end, tools such…
On automorphisms of flag spaces
Hans Havlicek, Klaus List, Corrado Zanella
We show that the automorphisms of the flag space associated with a 3-dimensional projective space can be characterized as bijections preserving a certain binary relation on the set…
Veronese Varieties over Fields with non-zero Characteristic: A Survey
Hans Havlicek
In the present survey we collect some recent results on nuclei of Veronese varieties and invariant subspaces of normal rational curves. We must assume, however, that the ground fie…
On embedded products of Grassmannians
Hans Havlicek, Corrado Zanella
Let and be two Grassmannians. The standard embedding is obtained by combining the Plücker and Segre embeddings. Given a further embedding $η: Γ'\t…
On linear morphisms of product spaces
Alessandro Bichara, Hans Havlicek, Corrado Zanella
Let be a linear morphism of the product of two projective spaces and into a projective space. Let be the Segre embedding of such a product. In this pape…
