Abstract: Abstract We study diagrammatic reducibility for the relative group presentations R n ( k , l , e ) = 〈 H , x | t 3 x k t 2 x e ( k… read more here.

Abstract: Abstract Excluding four exceptional cases, we determine the asphericity of the relative presentation for m ⩾ 2. If H = ⟨g, h⟩ ⩽ G, then the exceptional cases occur when H is isomorphic to C… read more here.
