题目: Harder-Narasimhan filtration of the bundles as Frobenius pull-back

报告人: 周明铄 杭州电子科技大学(讲师)

摘要: Let X be a smooth projective curve of genus g>1 over an algebraic closed field k of characteristic p>0. Let F: X->X be the absolute Frobenius morphism, and E a semistable vector bundles on X. It is natural to ask whether the length of the Harder-Narasimhan filtration of F^*(E) is at most p. In this talk, we construct a counterexample to above question.
