Sunto

Si considerano fibrati vettoriali reali con gruppo strutturale riducibile a Sp(n)· Sp(1)e a Sp(n)·tU(1)e si introducono classi caratteristiche relative a tali strutture mediante forme differenziali rappresentanti. Tali classi risultano generatori algebricamente indipenclenti dei quozienti modulo la 2-torsione degli anelli di coomologia intera dei rispettivi spazi classificanti, e si riducono mod. 2 a classi già introdotte. Si esamina in particolare il caso del fibrato tangente dello spazio proiettivo quaternionale.
