… We study Hartnell’s firefighter problem on infinite trees and characterise the branching
number in terms of the firefighting game. Using our results about trees, we give a partial
answer to a question of Martínez-Pedroza concerning firefighting on Cayley graphs. … We
show that for a Cayley graph with exponential growth of rate α we have λc = α. This implies that …
