摘要:
In this paper we analyze a list of general properties of waists and waist pairs in a pro-p group, these being subgroups or pairs of subgroups comparable in some sense with respect to inclusion with any open normal subgroup of the pro-p group. In the case of waist pairs of a pro-p group we get some characterizations of them, and give a way of building new waist pairs.
