InGrisha Perelman presented a new kind of differential Harnack inequality which involves both the (adjoint) linear heat equation and the Ricci flow.

This led to a completely new approach to the Ricci flow that allowed interpretation as a gradient flow which maximizes different entropy : Reto Müller. Di erential Harnack Inequalities and the Ricci Flow Reto Muller This is a preprint of the book published in EMS Series Lect.

[Reto Müller] -- "The text is a self-contained, modern introduction to the Ricci flow and the analytic methods to study it. It is primarily addressed to students who have a basic introductory knowledge of analysis.

The goal of this book is to explain this analytic tool in full detail for the two examples of the linear heat equation and the Ricci flow.

It begins with the original Li-Yau result, presents Hamilton's Harnack inequalities for the Ricci flow, and ends with Perelman's entropy formulas and space-time geodesics.4/5(1).
