Abstract

Let g(t)g(t), t[0,+)t\in [0, +\infty), be a solution of the normalized K\"ahler-Ricci flow on a compact K\"ahler nn-manifold MM with c1(M)>0c_{1}(M)>0 and initial metric g(0)2πc1(M)g (0)\in 2\pi c_{1}(M). If there is a constant CC independent of tt such that MRm(g(t))ndvtC, \int_{M}|Rm(g(t))|^{n}dv_{t}\leq C, then, for any tkt_{k}\to \infty, a subsequence of (M,g(tk))(M, g(t_{k})) converges to a compact orbifold (X,h)(X, h) with only finite many singular points {qj}\{q_{j}\} in the Gromov-Hausdorff sense, where hh is a K\"ahler metric on X\{qj}X\backslash \{q_{j}\} satisfying the K\"ahler-Ricci soliton equation, i.e. there is a smooth function ff such that Ric(h)h=ˉf,andf=ˉˉf=0.Ric(h)-h=\nabla\bar{\nabla}f, {\rm and}\it \nabla \nabla f=\bar{\nabla} \bar{\nabla} f=0.
