On the Conditions to Extend Ricci Flow
Consider {(M, g(t)), 0 ≤ t < T < ∞} as an unnormalized Ricci flow solution: dgij dt = −2Rij for t ∈ [0, T ). Richard Hamilton shows that if the curvature operator is uniformly bounded under the flow for all t ∈ [0, T ) then the solution can be extended over T . Natasa Sesum proves that a uniform bound of Ricci tensor is enough to extend the flow. We show that if Ricci is bounded from below, the...
متن کاملOn the conditions to extend Ricci flow(III)
Theorem 1 (Riemannian curvature ratio estimate). There exists a constant 0 = 0(m) with the following properties. Suppose K ≥ 0, { (X, g(t)),− 1 8 ≤ t ≤ K } is a Ricci flow solution on a complete manifold Xm, Q(0) = 1, and Q(t) ≤ 2 for every t ∈ [− 8 , 0]. Suppose T is the first time such that Q(T ) = 2, then there exists a point x ∈ X and a nonzero vector V ∈ TxX such that ∣∣∣∣∣log 〈V,V〉g(0) 〈V...
متن کاملMean Value Inequalities and Conditions to Extend Ricci Flow
This paper concerns conditions related to the first finite singularity time of a Ricci flow solution on a closed manifold. In particular, we provide a systematic approach to the mean value inequality method, suggested by N. Le [13] and F. He [11]. We also display a close connection between this method and time slice analysis as in [23]. As an application, we prove several inequalities for a Ric...
متن کاملGEOMETRIZATION OF HEAT FLOW ON VOLUMETRICALLY ISOTHERMAL MANIFOLDS VIA THE RICCI FLOW
The present article serves the purpose of pursuing Geometrization of heat flow on volumetrically isothermal manifold by means of RF approach. In this article, we have analyzed the evolution of heat equation in a 3-dimensional smooth isothermal manifold bearing characteristics of Riemannian manifold and fundamental properties of thermodynamic systems. By making use of the notions of various curva...
متن کاملRicci flow on Orbifolds
In this paper, we study the behavior of Ricci flows on compact orbifolds with finite singularities. We show that Perelman’s pseudolocality theorem also holds on orbifold Ricci flow. Using this property, we obtain a weak compactness theorem of Ricci flows on orbifolds under some natural technical conditions. This generalizes the corresponding theorem on manifolds. As an application, we can use K...
