Regular ovoids and Cameron-Liebler sets of generators in polar spaces
Maarten De Boeck, Jozefien D'haeseleer, Morgan Rodgers
Cameron-Liebler sets of generators in polar spaces were introduced a few years ago as natural generalisations of the Cameron-Liebler sets of subspaces in projective spaces. In this…
Cameron-Liebler sets in permutation groups
Jozefien D'haeseleer, Karen Meagher, Venkata Raghu Tej Pantangi
Consider a group acting on a set , the vector is a vector with the entries indexed by the elements of , and the -entry is 1 if maps to , and zero…
Cospectral mates for generalized Johnson and Grassmann graphs
Aida Abiad, Jozefien D'haeseleer, Willem H. Haemers +1
We provide three infinite families of graphs in the Johnson and Grassmann schemes that are not uniquely determined by their spectrum. We do so by constructing graphs that are cospe…
Blocking sets, minimal codes and trifferent codes
Anurag Bishnoi, Jozefien D'haeseleer, Dion Gijswijt +1
We prove new upper bounds on the smallest size of affine blocking sets, that is, sets of points in a finite affine space that intersect every affine subspace of a fixed codimension…
