A Poincaré duality type theorem for polyhedra
Annales de l'Institut Fourier, Tome 22 (1972) no. 4, p. 47-58
Si X est un polyèdre de dimension n, en employant des techniques géométriques, nous construisons des groupes H p (X) Δ et H p (X) Δ avec des isomorphismes naturels H p (X) Δ H n-p (X) et H p (X) Δ H n-p (X) induisant un accouplement d’intersection.Ces groupes donnent une interprétation géométrique des deux suites spectrales étudiées par Zeeman et nous permettent de prouver une conjecture de Zeeman à leur sujet.
If X is a n-dim polyhedran, then using geometric techniques, we construct groups H p (X) Δ and H p (X) Δ such that there are natural isomorphisms H p (X) Δ H n-p (X) and H p (X) Δ H n-p (X) which induce an intersection pairing. These groups give a geometric interpretation of two spectral sequences studied by Zeeman and allow us to prove a conjecture of Zeeman about them.
