Weak covering conjecture for infinite Cayley graphs
Weak covering conjecture for infinite Cayley graphs
Let be an infinite Cayley graph that is not quasi-isometric to . A graph is a cover of if there is a covering map from to ; write when the graphs are not isomorphic. Weak covering conjecture. Every infinite Cayley graph , not quasi-isometric to , covers an infinite transitive graph . This is a weak form of a question of Benjamini and Duminil-Copin concerning coverings of infinite transitive graphs by graphs of bounded girth. The proposed statement is disproved by possible counterexamples arising from Cayley graphs of strongly simple groups.
