Abstract

We consider the relative group presentation (Formula presented.), where (Formula presented.) and (Formula presented.). We show modulo a small number of exceptional cases exactly, when (Formula presented.) is aspherical. If (Formula presented.), then the exceptional cases occur when (Formula presented.) is isomorphic to one of (Formula presented.) or (Formula presented.).
