ℒ-optimal transportation for Ricci flow

Peter Topping
From the journal


We introduce the notion of ℒ-optimal transportation, and use it to construct a natural monotonic quantity for Ricci flow which includes a selection of other monotonicity results, including some key discoveries of Perelman [The entropy formula for the Ricci flow and its geometric applications, 2002] (both related to entropy and to ℒ-length) and a recent result of McCann and the author [Topping, Amer. J. Math.].
