For an end and a tree of a graph we denote respectively by and the maximum numbers of pairwise disjoint rays of and belonging to , and we define . In this paper we give partial answers—affirmative and negative ones—to the general problem of determining if, for a function mapping every end of to a cardinal such that , there exists a spanning tree of such that for every end of .
