On the divisibility of knot groups

Kunio Murasugi

Vol. 52 (1974), No. 2, 491–503
Abstract

Some conditions for the knot group to be an R-group, i.e., the group in which the extraction of roots is unique, will be discussed in this paper. In particular, the group of a product knot is an R-group iff the knot group of each component is an R-group. For a fibred knot, a sufficient condition for its group to be an R-group will be given.
