Automorphisms of a family of small $(q,8)$-graphs
Abstract:
For given integers $k\geq 2$ and $g\geq 3$ the $k$-regular graphs of girth $g$ are called $(k,g)$-graphs. In the cage problem one has to construct the smallest possible $(k,g)$-graph (with respect to the order). The smallest such graphs are called $(k,g)$-cages. It is known that the $(q+1,8)$-cages, when $q$ is an odd prime power, are arising as incidence graphs of generalized quadrangles, thus they are very symmetric in the sense of automorphisms and transitivity. There were a few attempts to construct small $(q,8)$-graphs from the $(q+1,8)$-cages as induced subgraphs. In this talk, maybe surprisingly, we show that a family of such $(q,8)$-graphs of order $2q(q^2-1)$ is not so symmetric in comparison with other families. More precisely, we show that their group of automorphisms has precisely $4$ orbits on the set of vertices.

In either case, we hope to see as many of you as possible (either in person or virtually) at our Friday gatherings. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Macaj@fmph.uniba.sk Tue, 03 Oct 2023 12:01:00 +0200 https://uniba.sk/ The ChemSkills project: enabling the green and digital skills transformation of the chemical...

From finite to infinite and back
Abstract:
This is not a talk about new results but rather a gentle introduction to another way of thinking. We will review Ramsey's theorem in its infinite form and deduce the finite from it and then use the result to show the existence of another graph number. The latter is not provable by finite methods. Time permitting we mention other results where the infinite is needed to prove the finite.  More information]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Skoviera@fmph.uniba.sk Mon, 02 Oct 2023 14:58:00 +0200 http://https://uniba.sk/en/comenius-university-news/news-detail/back_to_page/univerzita-komenskeho/article/na-falling-walls-lab-obsadili-vsetky-stupne-vitazov-studenti-univerzity-komenskeho/ At the Falling Walls Lab, Comenius University students took all steps on the winners’ podium ....
