285G, Lecture 12: High curvature regions of Ricci flow and κ-solutions
In previous lectures, we have established (modulo some technical details) two significant components of the proof of the Poincaré conjecture: finite time extinction of Ricci flow with surgery (Theorem...

285G, Lecture 18: The structure of high-curvature regions of Ricci flow
Having characterised the structure of -solutions, we now use them to describe the structure of high curvature regions of Ricci flow, as promised back in Lecture 12, in particular controlling their...

285G, Lecture 19: The structure of Ricci flow at the singular time, surgery,...
In the previous lecture, we studied high curvature regions of Ricci flows on some time interval , and concluded that (as long as a mild topological condition was obeyed) they all had canonical...
