Abstract: Harder-Narasimhan filtrations where first introduced for vector bundles on a Riemann surface. In fact people realized later those type of filtrations show up in other contexts. I will review the case of vector bundles, extract from this case a formalism that allows us to detect when such type of filtrations can appear and give a lot of examples of such filtrations in arithmetic geometry. In particular I will explain how I realized finite flat group schemes have such type of filtrations.
