[Construction d'une filtration de Harder–Narasimhan Frobenius non-scindée]
We construct an example of a vector bundle V over a smooth projective variety X such that for no , the Harder–Narasimhan filtration of splits, where is the Frobenius morphism of X.
Nous construisons un exemple de fibré vectoriel V au-dessus d'une variété projective lisse X tel que, pour tout , la filtration de Harder–Narasimhan de , où est le morphisme de Frobenius de X, est non-scindée.
