Calcolo della coomologia di alcuni spazi simmetrici con metodi puramente algebrici
Purely algebraic calculation of the De Rham cohomology for classifying spaces of SO and SO(k), following ideas of E. Cartan.
Characteristic Classes through Classical Invariant Theory.
Osservazioni sul tipo omotopico dei G-CW-complessi e dei G-ANR
We prove that a countable G-CW-complex is G-homotopically equivalent to a G-ANR, when G is a finite group with a free action.
