关于测地线上本征函数的积分

On integrals of eigenfunctions over geodesics

Xuehua Chen, Christopher D. Sogge

摘要:

若$(M,g)$是紧致黎曼曲面,则$L^2(M)$ -正规化本征函数$e_j$在定长测线段上的积分是一致有界的.此外,如果$(M,g)$具有负曲率,并且$γ(t)$是由弧长参数化的测地线,则$\R$上的测量$e_j(γ(t))\, dt$在作为本征值$\la_j\to \infty$的分布意义上趋于零,因此本征函数在周期测地线上的积分作为$\la_j\to \infty$趋于零。负曲率的假设对于后一个结果是必要的。

英文摘要:

If $(M,g)$ is a compact Riemannian surface then the integrals of $L^2(M)$-normalized eigenfunctions $e_j$ over geodesic segments of fixed length are uniformly bounded. Also, if $(M,g)$ has negative curvature and $γ(t)$ is a geodesic parameterized by arc length, the measures $e_j(γ(t))\, dt$ on $\R$ tend to zero in the sense of distributions as the eigenvalue $\la_j\to \infty$, and so integrals of eigenfunctions over periodic geodesics tend to zero as $\la_j\to \infty$. The assumption of negative curvature is necessary for the latter result.
