Abstract

We give a general geometrical procedure to construct nilpotent morphisms Phi : F -> F(d), with F a vector bundle on P-1, obtaining an analog of the Jordan canonical form. We investigate the possible splitting types of F in dependence on the degeneration behavior of Phi. Applications to nilpotent matrices with an arbitrary number of variables are also given.
