Lemnouar, Noui On Černikov-by-nilpotent groups. (English) Zbl 1162.20023 J. Algebra Appl. 5, No. 2, 119-123 (2006). Let \(\Omega\) be a class of groups. Define \((\Omega,\infty)\) to be the class of all groups in which every infinite subset contains two distinct elements which generate an \(\Omega\)-group. In the paper under review, the author studies finitely generated solvable groups in the class \((\Omega,\infty)\) whenever \(\Omega\) is either the class of Chernikov groups (denoted by \(\check {C}\)), or the class of Chernikov-by-nilpotent groups (denoted by \(\check {C}N\)). The class of finite groups and finite-by-nilpotent groups are denoted by \(F\) and \(FN\), respectively.The author proves the following:Theorem 1. Let \(G\) be a finitely generated solvable group. Then \(G\in (\check {C}, \infty)\) if and only if \(G\in F\).Theorem 2. Let \(G\) be a finitely generated solvable group. Then \(G\in (\check {C}N, \infty)\) if and only if \(G\in FN\).
