If E=E-p->X is a p-fiber space (hp-fiber space), then there exists an inverse system of hp-fiber spaces E^[n] such that the homtopy groups pi(E^[n])=pi(E)if i<=n and pi(E^[n])=0 if i>n (pi(E^[n])=pi(E)if i<=n and pi(E[n])=X^i if i>n). If X is a point then th inverse system is the Postnikov tower of E.

Abstract
If E=E-p->X is a p-fiber space (hp-fiber space), then there exists an inverse system of hp-fiber spaces E^[n] such that the homtopy groups pi(E^[n])=pi(E)if i<=n and pi(E^[n])=0 if i>n (pi(E^[n])=pi(E)if i<=n and pi(E[n])=X^i if i>n). If X is a point then th inverse system is the Postnikov tower of E.File in questo prodotto:
