SymOmega

I rarely give talks using Beamer theses days, but the majority of the talks I see at conferences and in seminars, do.

We are advertising a 3 year postdoctoral position at the University of Western Australia to work at the interface of finite geometry and Ramsey theory.

In a post a few years ago, I described how to install nauty on an iPhone using an app that provides a Linux shell.

This is a follow-up to the work some of us at UWA have been doing on subproblems to do with the “synchronising hierarchy” of permutation groups.

Geertrui Van de Voorde from the University of Canterbury (NZ) visited us in November 2022 for two weeks, one week of which I had covid, but we managed to begin a project which would later become a paper (together with Jesse Lansdown).

I’ve just returned to Perth after giving one of the plenary talks at the “10th Slovenian Conference on Graph Theory” held in small ski-resort town of Kranjska Gora.

I am currently on sabbatical, and the longest research visit is occurring now, at the Technical University of Delft.

So my first international trip since Covid happened has been to a CS/Maths Research Centre “Schloss Dagstuhl” located in a fairly rural area in Germany.

How often have you been out somewhere, maybe at a restaurant or pub, and suddenly needed to generate some graphs, or determine the canonical labelling of a graph that has come up in conversation, only to be foiled because you don’t have your laptop with y…

Recently, Michael Giudici, Jesse Lansdown, Gordon Royle and I have constructed a couple of examples of synchronising groups that are radically different from the known examples.
