Topic:

A uniqueness theorem for asymptotically cylindrical shrinking Ricci solitons

Description:

I will discuss some recent joint work with Lu Wang in which we prove that a shrinking gradient Ricci soliton which agrees to infinite order at spatial infinity with a generalized cylinder along some end must be isometric to the cylinder on that end. When the shrinker is complete, it must be globally isometric to the cylinder or else to a Z_2-quotient. This work belongs to a larger program aimed at obtaining a structural classification of complete noncompact shrinking solitons.
