In this paper we introduce and study the relative cyclic subgroup commutativity degrees of a finite group. We show that there is a finite group with n such degrees for all n ∈ ℕ* \ {2} and we indicate ...
It is shown that an end-irreducible 3-manifold each of whose boundary components is compact and whose fundamental group contains an infinite cyclic normal subgroup is Seifert fibered. Journal ...
