我们证明了Hile和Protter的一个特征值不等式的纯代数形式,并导出了流形上拉普拉斯- Beltrami算子特征值差的边界推论.我们显着改善杨和丘,李,和哈雷尔早期的界限。
We prove a purely algebraic version of an eigenvalue inequality of Hile and Protter, and derive corollaries bounding differences of eigenvalues of Laplace– Beltrami operators on manifolds. We significantly improve earlier bounds of Yang and Yau, Li, and Harrell.
