Generalized Hamming weights of additive codes and geometric counterparts
Jozefien D'haeseleer, Sascha Kurz
We consider the geometric problem of determining the maximum number of -spaces in the projective space such that each subspace of c…
A note on the classification of classical distance-regular graphs of negative type and the non-existence of hemisystems
Sam Adriaensen, Jan De Beule, Jozefien D'haeseleer +1
DISCLAIMER: Due to an error in the literature, we cannot be sure that the conclusions drawn in this paper are correct. The goal of this note is to connect some interesting results…
Chromatic Number of Grassmann Graphs and MRD codes
Jozefien D'haeseleer, Francesco Pavese, Paolo Santonastaso +1
In this paper we investigate the chromatic number of the Grassmann graphs and of their powers, denoted . In this graph, the vertices correspond to the -dimensional s…
On the Chromatic Number of Grassmann Graphs
Jozefien D'haeseleer, Vladislav Taranchuk
In this paper we study the chromatic number of the Grassmann graphs . We show that , which is analogous to the…
Cameron-Liebler sets of generators in the Klein quadric
Jozefien D'haeseleer, Jonathan Mannaert, Leo Storme
We investigate Cameron-Liebler sets of planes in the Klein quadric in PG. We prove that there are many examples of such Cameron-Liebler sets of planes in the Klei…
