Title: | Criteria for existence of stable parahoric SOn, Spn and Spin bundles on P1 |
Authors: | Yashonidhi Pandey |
Issue Date: | 2014 |
Publisher: | Journal of the Ramanujan Mathematical Society |
Abstract: | Let p : Y ~ X be a Galois cover of smooth projective curves over C with Galois group r. This paper is devoted to the study of principal orthogonal and symplectic bundles E on Y to which the action of r on Y lifts. We notably describe them intrinsically in terms of objects defined on X and call these objects parahoric bundles. We give necessary and sufficient conditions for the non-emptiness of the moduli of stable (and semi-stable) parahoric special orthogonal, symplectic and spin bundles on the projective line JP>1 |
