Abstract
A well known theorem of R. Baer states that if G is a group and G/Z n (G) is finite, then γ n+1 (G) is finite. In this article, we extend this theorem for groups G that have subgroups A of Aut(G) such that A/Inn(G) is finitely generated or is of finite special rank. Furthermore, some new upper bounds for |γ n+1 (G)| and |γ n+1 (G, A)| are presented.
