Title: Infinite cubic vertex-transitive graphs

Staðsetning: Naustið, Endurmenntun (hér)
Tími: Fimmtudagur 21. maí, klukkan 15:00-16:00.


Tutte’s two papers from 1947 and 1959 on cubic graphs were the starting point of the in-depth study of the interplay between the structure of a group and the structure of a graph that the group acts on. In this talk I will describe applications of Tutte’s ideas where it is assumed that the graph is infinite and the stabilizers of vertices are infinite.
