拉格朗日中曲率流的自相似解和平移孤子

Self-similar solutions and translating solitons for Lagrangian mean curvature flow

Dominic Joyce, Yng-Ing Lee, Mao-Pei Tsui

摘要:

我们构造了许多拉格朗日中曲率流的自相似和平移孤子,包括自膨胀孤子和在拉格朗日角上具有任意小振荡的平移孤子。我们得到的平移孤子在里奇流中起着与雪茄孤子相同的作用,对研究拉格朗日中曲率流的规律性有重要意义。给定C^n中的两个特征角之和小于pi的横拉格朗日平面R^n,我们证明了这对平面存在一个拉格朗日自展式渐近解.这些自膨胀器的马斯洛夫类为零。因此,它们可以作为局部模型的手术拉格朗日中曲率流。还构造了具有不同拓扑结构的自收缩器和自膨胀器族。本文概括了安西奥、乔伊斯、劳勒、李和王的工作。

英文摘要:

We construct many self-similar and translating solitons for Lagrangian mean curvature flow, including self-expanders and translating solitons with arbitrarily small oscillation on the Lagrangian angle. Our translating solitons play the same role as cigar solitons in Ricci flow, and are important in studying the regularity of Lagrangian mean curvature flow. Given two transverse Lagrangian planes R^n in C^n with sum of characteristic angles less than pi, we show there exists a Lagrangian self-expander asymptotic to this pair of planes. The Maslov class of these self-expanders is zero. Thus they can serve as local models for surgeries on Lagrangian mean curvature flow. Families of self-shrinkers and self-expanders with different topologies are also constructed. This paper generalizes the work of Anciaux, Joyce, Lawlor, and Lee and Wang.
