On the local-indicability cohen-lyndon theorem
For a group H and a subset X of H, we let HX denote the set {hxh?1 | h ? H, x ? X}, and when X is a free-generating set of H, we say that the set HX is a Whitehead subset of H. For a group F and an element r of F, we say that r is Cohen-Lyndon aspherical in F if F{r} is a Whitehead subset of the sub...
