图的本征函数与量子唯一遍历性

Graph Eigenfunctions and Quantum Unique Ergodicity

Shimon Brooks, Elon Lindenstrauss

摘要:

我们应用我们以前的文件的技术,研究联合本征函数的Laplacian和一个Hecke算子的紧同余曲面,联合本征函数的两个部分Laplacian的紧同余$\mathbb{H}\times\mathbb{H}$。在这两种情况下,我们表明,量子极限措施,这样的序列的本征函数进行正熵几乎每一个遍历组件。与第二位作者的先前工作一起,这意味着这些函数的量子唯一遍历性。

英文摘要:

We apply the techniques of our previous paper to study joint eigenfunctions of the Laplacian and one Hecke operator on compact congruence surfaces, and joint eigenfunctions of the two partial Laplacians on compact quotients of $\mathbb{H}\times\mathbb{H}$. In both cases, we show that quantum limit measures of such sequences of eigenfunctions carry positive entropy on almost every ergodic component. Together with prior work of the second named author, this implies Quantum Unique Ergodicity for such functions.
