Fano流形的里奇曲率的下确界

Greatest lower bounds on the Ricci curvature of Fano manifolds

Gábor Székelyhidi

摘要:

在Fano流形M上研究了可能的t的上确界,使得在c_1(M)中存在一个Kähler度量,其里奇曲率由t下界.这被证明是相同的Aubin的连续性路径的最大存在时间寻找Kähler-Einstein度量。我们证明了在P^2上在一点爆破时,这个上确界是6/7,并给出了其他流形的上界。

英文摘要:

On a Fano manifold M we study the supremum of the possible t such that there is a Kähler metric in c_1(M) with Ricci curvature bounded below by t. This is shown to be the same as the maximum existence time of Aubin's continuity path for finding Kähler-Einstein metrics. We show that on P^2 blown up in one point this supremum is 6/7, and we give upper bounds for other manifolds.
