Volume growth estimates of gradient Ricci solitons

Pak-Yeung Chan, Zilu Ma, Yongjia Zhang

In this paper, we survey the volume growth estimates for shrinking, steady, and expanding gradient Ricci solitons. Together with the known results, we also prove some new volume gr…

The rate of -convergence for Ricci flows with closed and smooth tangent flows

Pak-Yeung Chan, Zilu Ma, Yongjia Zhang

This article is a continuation of [CMZ21b], where we proved that a Ricci flow with a closed and smooth tangent flow has unique tangent flow, and its corresponding forward or backwa…

An optimal volume growth estimate for noncollapsed steady gradient Ricci solitons

Richard H. Bamler, Pak-Yeung Chan, Zilu Ma +1

In this paper, we prove a volume growth estimate for steady gradient Ricci solitons with bounded Nash entropy. We show that such a steady gradient Ricci soliton has volume growth r…

A uniform Sobolev inequality for ancient Ricci flows with bounded Nash entropy

Pak-Yeung Chan, Zilu Ma, Yongjia Zhang

This note is a continuation of [CMZ21]. We shall show that an ancient Ricci flow with uniformly bounded Nash entropy must also have uniformly bounded -functional. Consequently,…

Ancient Ricci flows with asymptotic solitons

Pak-Yeung Chan, Zilu Ma, Yongjia Zhang

We study ancient Ricci flows which admit asymptotic solitons in the sense of Perelman. We prove that the asymptotic solitons must coincide with Bamler's tangent flows at infinity.…

Perelman's entropy on ancient Ricci flows

Zilu Ma, Yongjia Zhang

In [ZY2], the second author proved Perelman's assertion, namely, for an ancient Ricci flow with bounded and nonnegative curvature operator, bounded entropy is equivalent to noncoll…
