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.
