摘要翻译:
研究了Fano流形上沿Kahler Ricci流的一些估计。利用这些估计,我们直接证明了当标准类的$\alpha$-不变量大于$\frac{n}{n+1}$时,Kahler Ricci流的收敛性。应用这些收敛性定理,我们可以给出这类Fano流形上的Calabi猜想的流证明。特别是用流方法证明了许多Fano曲面上Kahler Einstein度量的存在性。注意,这个几何结论(基于同样的假设)是由G.Tian在较早的时候通过椭圆法建立的。然而,一个基于Kahler Ricci流的新证明本身应该仍然很有趣。

英文摘要:
We study some estimates along the Kahler Ricci flow on Fano manifolds. Using these estimates, we show the convergence of Kahler Ricci flow directly if the $\alpha$-invariant of the canonical class is greater than $\frac{n}{n+1}$. Applying these convergence theorems, we can give a flow proof of Calabi conjecture on such Fano manifolds. In particular, the existence of Kahler Einstein metrics on a lot of Fano surfaces can be proved by flow method. Note that this geometric conclusion (based on the same assumption) was established earlier via elliptic method by G. Tian. However, a new proof based on Kahler Ricci flow should be still interesting in its own right.
