Description |
In this talk I will discuss the pull-back of a semistable vector bundle on a smooth projective curve under the Frobenius morphism. I will describe explicit examples of stable rank two syzygy bundles which are isomorphic to their Frobenius pull-back (joint work with Kaid) and give two classes of examples of bundles on a relative curve over the affine line where generically the bundle is strongly semistable, but not so for special points (joint work with Staebler). |
