Sunto
-- Il fibrato di Tango è definito come pull-back del fibrato di Cayley $C$ su una e quadrica liscia $Q_5$ in $\mathbb{P}_6$ attraverso una funzione $f$ definita in caratteristica 2 che fattorizza il morfismo di Frobenius $\varphi$. La coomologia di $T$ è calcolata in termini di $S \otimes C$, $\varphi^*(C)$, $\text{Sym}^2(C)$ e $C$, che si studiano con il teorema di Borel-Bott-Weil.
