Journal ArticleDOI
On the Hitchin morphism in positive characteristic
Yves Laszlo,Christian Pauly +1 more
TL;DR: In this article, the Hitchin morphism, which associates to a Higgs bundle its characteristic polynomial, has a nontrivial deformation over the affine line, constructed by considering the moduli stack of t-connections on vector bundles on X and an analogue of the p-curvature.
Journal ArticleDOI
On Frobenius-destabilized rank-2 vector bundles over curves
Herbert Lange,Christian Pauly +1 more
TL;DR: In this article, it was shown that for any line bundle L over X, the rank-p vector bundle FL is stable and the rational map V has base points, i.e., there exist stable bundles E over X1 such that FE is not semistable.
Journal ArticleDOI
Self-duality of Coble's quartic hypersurface and applications
TL;DR: The moduli space M0 of semi-stable rank 2 vector bundles with fixed trivial determinant over a non-hyperelliptic curve C of genus 3 is isomorphic to a quartic hypersurface in P 7 (Coble's quartic).
Journal ArticleDOI
The action of the Frobenius map on rank 2 vector bundles in characteristic 2
Yves Laszlo,Christian Pauly +1 more
TL;DR: In this article, the absolute Frobenius induces a rational map $F$ on the moduli space of rank 2 vector bundles with fixed trivial determinant, which is isomorphic to projective space of dimension 3.
