摘  要：In this talk, we give an overall description of the construction of the collapsed flying-wing-like steady gradient solitons, as well as the high dimension non-collapsed steady gradient solitons. In particular, we show that the asymptotic cone angle of the 3D flying wings can take any value between (0,\pi).

摘  要：In this talk, we talk about the proof of the O(2)-symmetry of 3D steady gradient solitons. The proof consists of four parts: the asymptotic analysis at infinity, the symmetry improvement theorem, the decay of the lie derivative, and evolving a vector field to a killing field by a heat equation.
