COMPUTING HOMOTOPY GROUPS OF A HOMOTOPY PULLBACK

Abstract Secondary structure of an exact sequence of Maya-Vietoris type associated to a simply-connected homotopy pullback is exploited to yield a technique for computing its higher homotopy groups. The information required consists of the homotopy groups of the original spaces, the homomorphisms induced by the given maps and certain matrix Toda brackets.
