黎曼流形上一类算子的低阶特征值估计
ESTIMATES FOR LOWER ORDER EIGENVALUES OF A CLASS OF OPERATORS ON RIEMANNIAN MANIFOLD

本文研究n(≥ 2)维完备黎曼流形M的有界区域？上算子的低阶特征值估计问题.利用Rayleigh-Ritz不等式,获得了该算子低阶特征值的万有不等式.
In this paper,we investigate the boundary value problem of the operator.By the Rayleigh-Ritz inequality,we obtain universal inequalities for lower order eigenvalues of these operator
