A note on the chromatic number of Kneser graphs on chambers of projective planes and incidence-free sets
Philipp Heering, Klaus Metsch, Vladislav Taranchuk +1
The paper provides an elementary proof of a perfect matching in the incidence graph of a symmetric design, links the chromatic number of Kneser graphs on projective‑plane chambers…
On Reed-Muller subcodes, Grassmannian partitions and sum-free functions
Philipp Heering, Christian Kaspers, Vladislav Taranchuk
A function is called th-order sum-free if the sum of its values over any -dimensional affine subspace of is non-…
Cocliques in the Kneser graph on -flags of PG
Philipp Heering
In the finite projective space PG we consider flags of type , that is, pairs consisting of an -space and an -space that are incident. Two…
Line-parallelisms of PG from Preparata-like codes
Philipp Heering, Vladislav Taranchuk
Partitions of the binary linear Hamming code into Preparata-like codes are known to induce line-parallelisms of PG. In this paper, we show that if is any Preparata-like…
On the ErdÅs-Ko-Rado problem of flags with type of finite sets
Philipp Heering
A flag of a finite set is a set of non-empty, proper subsets of , such that or for all . Two flags and of are opp…
The largest sets of non-opposite chambers in spherical buildings of type
Jan De Beule, Philipp Heering, Sam Mattheus +1
The investigation into large families of non-opposite flags in finite spherical buildings has been a recent addition to a long line of research in extremal combinatorics, extending…
