WebbIn this note, we prove an ɛ-regularity theorem for the Ricci flow. Let (M n,g(t)) with t ∊ [−T,0] be a Ricci flow, and let H x0 (y,s) be the conjugate heat kernel centered at some point (x 0,0) in the final time slice.By substituting H x0 (−,s) into Perelman's W-functional, we obtain a monotone quantity W x0 (s) that we refer to as the pointed entropy.
