Názov: Small regular graphs of given girth as lifts of dipoles

Termín: 4.12.2020, 13:00 hod., MS Teams (AGT in Bratislava team, scheduled meeting)

Abstrakt:
One of the approaches of finding small regular graphs of given girth $g$ are lifting constructions. In the talk we examine our constructions of graphs of girth 6 obtained by lifting dipoles with suitable voltage assignments and achieving the order of graphs provided by Abreu, Funk, Labbate and Napolitano in 2006. We will also discuss potential of such constructions for larger girth, especially for $g = 8$.

This work is joint with Štefan Gyürki, Jana Šiagiová and Jozef Širáň

Due to recent restrictions imposed on us in response to the worsening of the situation with Covid infections in Slovakia, we will switch to distance mode. You will receive an MS Teams link over which you will be able to follow the presentation, ask questions, comment, and possibly even offer some solutions. While it is not better than being personally in the lecture room, it is not a terrible way to keep in touch either. Let us hope that we will soon be able to attend the meetings in person.
