Abstract: We will talk about the construction of Harder-Narasimhan stratification on the B_{dR}^+-Grassmannian and study its basic geometric properties, such as non-emptiness, dimension and relation with other stratifications, which  generalizes the work of Dat-Orlik-Rapoport,  Cornut-Peche Irissarry, Nguyen-Viehmann and Shen.  This is a joint work in progress with Jilong Tong.
