黎曼流形上拉普拉斯算子的特征值

Eigenvalues of the Laplacian on Riemannian manifolds

Qing-Ming Cheng, Xuerong Qi

摘要:

对于完备黎曼流形$M$中具有分片光滑边界的有界区域$Ω$,研究了Laplacian算子的Dirichlet本征值问题的特征值问题.利用本征函数代替Rayleigh-Ritz公式形成$L^2(Ω)$的规范正交基这一事实,得到了拉普拉斯算子的本征值不等式.特别地,对于低阶特征值,我们的结果推广了Chen和Cheng \cite{CC}的结果.

英文摘要:

For a bounded domain $Ω$ with a piecewise smooth boundary in a complete Riemannian manifold $M$, we study eigenvalues of the Dirichlet eigenvalue problem of the Laplacian. By making use of a fact that eigenfunctions form an orthonormal basis of $L^2(Ω)$ in place of the Rayleigh-Ritz formula, we obtain inequalities for eigenvalues of the Laplacian. In particular, for lower order eigenvalues, our results extend the results of Chen and Cheng \cite{CC}.
