On the sunflower bound for -spaces, pairwise intersecting in a point
Aart Blokhuis, Maarten De Boeck, Jozefien D'haeseleer
A -intersecting constant dimension subspace code is a set of -dimensional subspaces in a projective space PG(n,q), where distinct subspaces intersect in a -dimensional…
Hilton-Milner results in projective and affine spaces
Jozefien D'haeseleer
In this article, we analyse maximal sets of -spaces, in PG(n,q) and AG(n,q), , that pairwise meet in at least a -space. It is known that for both PG(n,q) and AG(n,q…
Neumaier graphs with few eigenvalues
Aida Abiad, Bart De Bruyn, Jozefien D'haeseleer +1
A Neumaier graph is a non-complete edge-regular graph containing a regular clique. In this paper we give some sufficient and necessary conditions for a Neumaier graph to be strongl…
On the chromatic number of two generalized Kneser graphs
Jozefien D'haeseleer, Klaus Metsch, Daniel Werner
We determine the chromatic number of some graphs of flags in buildings of type , namely of the Kneser graphs of flags of type in the vector spaces for $q\g…
On absolute points of correlations in PG
Jozefien D'haeseleer, Nicola Durante
Let be a -dimensional vector space over a field . Sesquilinear forms over have been largely studied when they are reflexive and hence give rise to a (pos…
Maximal sets of -spaces pairwise intersecting in at least a -space
Jozefien D'haeseleer, Giovanni Longobardi, Ago-Erik Riet +1
In this paper, we analyze the structure of maximal sets of -dimensional spaces in pairwise intersecting in at least a -dimensional space, for $3 \leq k…
Cameron-Liebler -sets in
Jozefien D'haeseleer, Ferdinand Ihringer, Jonathan Mannaert +1
We study Cameron-Liebler -sets in the affine geometry, so sets of -spaces in . This generalizes research on Cameron-Liebler -sets in the projective geomet…
Cameron-Liebler line classes in AG(3,q)
Jozefien D'haeseleer, Jonathan Mannaert, Leo Storme +1
The study of Cameron-Liebler line classes in PG() arose from classifying specific collineation subgroups of PG(). Recently, these line classes were considered in new sett…
