关于结点集最近下界的一个注记

A Remark on Recent Lower Bounds for Nodal Sets

Dan Mangoubi

摘要:

最近,Sogge-Zelditch和Colding-Minicozzi给出了本征函数节点集大小的新的幂律下界.这篇短文的目的是指出第三种方法来获得节点集体积的幂律下界。我们的方法是基于本征函数的Donnelly-February man增长界和我们在以前的工作中证明的增长与体积的关系。

英文摘要:

Recently, Sogge-Zelditch and Colding-Minicozzi gave new power law lower bounds on the size of the nodal sets of eigenfunctions. The purpose of this short note is to point out a third method to obtain a power law lower bound on the volume of the nodal sets. Our method is based on the Donnelly-Fefferman growth bound for eigenfunctions and a growth vs. volume relation we proved in a previous work.
