Abstract

It is shown that an equivariant Lagrangian sphere with a positivity condition on its Ricci curvature develops a type-II singularity under the Lagrangian mean curvature flow that rescales to the product of a grim reaper with a flat Lagrangian subspace. In particular this result applies to the Whitney spheres.

惠特尼球的拉格朗日平均曲率流

证明了具有正里奇曲率条件的等变拉格朗日球在拉格朗日平均曲率流下具有ii型奇点，该奇异流可缩放为死神与平坦拉格朗日子空间的乘积。这个结果特别适用于惠特尼球。
