Hunter College, City University of New York [Image source] The Special Session on Infinite Permutation Groups, Totally Disconnected Locally Compact Groups and Geometric Group Theory organised by Simon Smith (University of Lincoln) and Delaram Kahrobaei (City University of New York) took place this weekend, as part of the huge American Mathematical Society Spring Eastern Sectional Meeting held at Hunter College, City University of New York.
The idea behind the special session was to bring together three areas of infinite group theory that share a powerful tool: the analysis of group structure through an action on a locally finite graph. Subdegree-finite permutation groups act on an orbital graph, finitely generated groups act on a Cayley graph, and compactly generated totally disconnected locally compact groups act on a Cayley–Abels graph.
In the Special Session there were speakers from across the world: USA, Australia, Europe and South America. The talks were excellent. James Maynard (University of Oxford) gave the…
