设是一个射影丛。我们用Cao(Elliptic and Parabolic methods in geometry(Minneapolis,MN,1994),A K Peters,韦尔斯利,1996)和Koiso(Recent topics in differential and analytic geometry.纯数学高级研究,波士顿,1990年)。本文证明了具有半径的透镜空间是自相似解。我们还证明了存在一对临界半径,满足以下条件。透镜空间是自收缩的,如果是自膨胀的,则从的Ricci平均曲率流坍缩到f的0-截面和f的-截面。本文给出了Ricci平均曲率流的显式例子。
Letbe a projective bundle overwith. We denotebyand endow it with theU(n)-invariant gradient shrinking Kähler Ricci soliton structure constructed by Cao (Elliptic and parabolic methods in geometry (Minneapolis, MN, 1994), A K Peters, Wellesley, 1996) and Koiso (Recent topics in differential and analytic geometry. Advanced studies in pure mathematics, Boston, 1990). In this paper, we show that lens spacewith radiusrembedded inis a self-similar solution. We also prove that there exists a pair of critical radii, which satisfies the following. The lens spaceis a self-shrinker ifand self-expander if, and the Ricci-mean curvature flow emanating fromcollapses to the 0-section ofifand to the-section ofif. This paper gives explicit examples of Ricci-mean curvature flows.
