A Remark on Frobenius Descent for Vector Bundles
نویسندگان
چکیده
We give a class of examples of a vector bundle on a relative smooth projective curve over SpecZ such that for infinitely many prime reductions the bundle has a Frobenius descent, but the generic restriction in characteristic zero is not semistable. Mathematical Subject Classification (2000): primary: 14H60, secondary: 13A35.

On Deep Frobenius Descent and Flat Bundles
Let R be an integral domain of finite type over Z and let f : X → SpecR be a smooth projective morphism of relative dimension d ≥ 1. We investigate, for a vector bundle E on the total space X , under what arithmetical properties of a sequence (pn, en)n∈N, consisting of closed points pn in SpecR and Frobenius descent data Epn ∼= F n(F) on the closed fibers Xpn , the bundle E0 on the generic fibe...
متن کاملOn vector bundles destabilized by Frobenius pull-back
Let X be a smooth projective curve of genus g > 1 over an algebraically closed field of positive characteristic. This paper is a study of a natural stratification, defined by the absolute Frobenius morphism of X, on the moduli space of vector bundles. In characteristic two, there is a complete classification of semi-stable bundles of rank 2 which are destabilized by Frobenius pull-back. We also...
متن کاملModuli of Vector Bundles on Curves in Positive Characteristic
Let X be a projective curve of genus 2 over an algebraically closed field of characteristic 2. The Frobenius map on X induces a rational map on the moduli space of rank-2 bundles. We show that up to isomorphism, there is only one (up to tensoring by an order two line bundle) semi-stable vector bundle of rank 2 with determinant equal to a theta characteristic whose Frobenius pull-back is not sta...

Let X be a smooth projective curve of genus g ≥ 2 defined over an algebraically closed field k of characteristic p > 0. For p sufficiently large (explicitly given in terms of r, g) we construct an atlas for the locus of all Frobenius-destabilized bundles (i.e. we construct all Frobenius-destabilized bundles of degree zero up to isomorphism). This is done by exhibiting a surjective morphism from...
متن کاملThe Frobenius map , rank 2 vector bundles and Kummer ’ s quartic surface in characteristic 2 and 3 Yves Laszlo and Christian Pauly
Our interest in the diagram (1.1) comes from questions related to the action of the Frobenius map on vector bundles like e.g. surjectivity of V , density of Frobenius-stable bundles, loci of Frobenius-destabilized bundles (see [LP]). These questions are largely open when the rank of the bundles, the genus of the curve or the characteristic of the field are arbitrary. In [LP] we made use of the ...
