摘要: We answer a question of Bartholdi, Siegenthaler and Zalesskii, showing that the congruence subgroup problem for branch groups is independent action on tree. prove topology group determined by group; specifically, its structure graph, an object first introduced Wilson. also give more natural definition this graph.
