Kahler Einstein流形中的极小Lagrange环面

Minimal Lagrangian tori in Kahler Einstein manifolds

Edward Goldstein

摘要:

本文利用Kahler-Einstein流形上的保结构环面作用来构造极小拉格朗日子流形。我们的主要结果是:设N^2n是具有有效T^n作用量的正数量曲率的Kahler-Einstein流形.则T作用的正则轨道L是N的极小拉格朗日子流形。此外,在T^n中存在一个(n-1)-环面T^n-1,在N中存在一列非平坦的浸入极小拉格朗日环面L_k,在T^n-1 s. t下不变. L_k局部收敛于L(特别是当k趋于无穷大时,L_k的截面曲率的上确界和L_k与L之间的距离趋于0)。

英文摘要:

In this paper we use structure preserving torus actions on Kahler-Einstein manifolds to construct minimal Lagrangian submanifolds. Our main result is: Let N^2n be a Kahler-Einstein manifold with positive scalar curvature with an effective T^n-action. Then precisely one regular orbit L of the T-action is a minimal Lagrangian submanifold of N. Moreover there is an (n-1)-torus T^n-1 in T^n and a sequence of non-flat immersed minimal Lagrangian tori L_k in N, invariant under T^n-1 s.t. L_k locally converge to L (in particular the supremum of the sectional curvatures of L_k and the distance between L_k and L go to 0 as k goes to infinity.
