殆Calabi-Yau流形中的广义Lagrange中曲率流

Generalized Lagrangian mean curvature flows in almost Calabi-Yau manifolds

Jun Sun, Liuqing Yang

摘要:

本文研究了T。贝恩德我们证明了这种流动的奇异性的特点是第二基本型。对于几乎Calabi-Yau流形上具有零Maslov类的广义Lagrange中曲率流,我们还证明了在奇点处的重标流收敛于一个特殊Lagrange锥的有限并.作为一个推论,对于这样的流,不存在有限时间的I型奇点。

英文摘要:

In this paper, we study the generalized Lagrangian mean curvature flow in almost Einstein manifold proposed by T. Behrndt. We show that the singularity of this flow is characterized by the second fundamental form. We also show that the rescaled flow at a singularity converges to a finite union of Special Lagrangian cones for generalized Lagrangian mean curvature flow with zero-Maslov class in almost Calabi-Yau manifold. As a corollary, there is no finite time Type-I singularity for such a flow.
