Adjunction of n-equivalences and triad connectivity.

Peter J. Witbooi (1995)

Publicacions Matemàtiques

Similarity:

We prove a new adjunction theorem for n-equivalences. This theorem enables us to produce a simple geometric version of proof of the triad connectivity theorem of Blakers and Massey. An important intermediate step is a study of the collapsing map S∨X → S, S being a sphere.
