题目：Harder-Narasimhan filtration for non-Euclidean lattices

报告人：陈华一教授（法国巴黎七大）

Abstract: Harder-Narasimhan filtration is a classic notion in the theory of vector bundles over projective curves. In the setting of Euclidean lattices, an arithmetic analogue of this construction has been proposed by Stuhler and Grayson. For lattices in a general finite-dimensional normed vector space, the perfect analogue of Harder-Narasimhan filtration was missing. In this talk, I will explain a recent joint work with Atsushi Moriwaki, where we propose a semi-stability condition for general lattices, which allows to obtain a precise analogue of the result of Harder and Narasimhan.
