On the asphericity of a family of positive relative group presentations

Aldwaik, Suzana; Edjvet, Martin

Abstract

Excluding four exceptional cases, the asphericity of the relative presentation P= ?G; x|xmgxh? for m ? 2 is determined. If H = ?g; h? ? G, then the exceptional cases occur when H is isomorphic to C5 or C6.
