A modular equality for Cameron-Liebler line classes in projective and affine spaces of odd dimension

Jan De Beule, Jonathan Mannaert

In this article we study Cameron-Liebler line classes in PG $(n, q)$ and AG $(n, q)$ , objects also known as boolean degree one functions. A Cameron-Liebler line class $L$ is…

On Local Operations that Preserve Symmetries and on Preserving Polyhedrality of Embeddings

Gunnar Brinkmann, Heidi Van den Camp

We prove that local operations that preserve all symmetries, as e.g. dual, truncation, ambo, or join,, as well as local operations that preserve all symmetries except orientation r…

Cameron-Liebler k-sets in subspaces and non-existence conditions

Jan De Beule, Jonathan Mannaert, Leo Storme

In this article we generalize the concepts that were used in the PhD thesis of Drudge to classify Cameron-Liebler line classes in PG $(n, q), n \geq 3$ , to Cameron-Liebler sets of $k$ …

New bounds for Ramsey numbers $R (K_{k} - e, K_{l} - e)$

Jan Goedgebeur, Steven Van Overberghe

Let $R (H_{1}, H_{2})$ denote the Ramsey number for the graphs $H_{1}, H_{2}$ , and let $J_{k}$ be $K_{k} - e$ . We present algorithms which enumerate all circulant and block-circulant Ramsey grap…

Minimal codewords arising from the incidence of points and hyperplanes in projective spaces

Daniele Bartoli, Lins Denaux

Over the past few years, the codes $C_{n - 1} (n, q)$ arising from the incidence of points and hyperplanes in the projective space $PG (n, q)$ attracted a lot of attenti…

The Minimality of the Georges-Kelmans Graph

Gunnar Brinkmann, Jan Goedgebeur, Brendan D. McKay

In 1971, Tutte wrote in an article that "it is tempting to conjecture that every 3-connected bipartite cubic graph is hamiltonian". Motivated by this remark, Horton constructed a c…
