摘    要:考虑某类微分系统特征值(又称谱)的上界估计,利用分部积分、Rayleigh定理和不等式估计等方法和技巧,获得了用前m个特征值来估计第m+1个特征值的上界的不等式,其估计系数与区域的几何度无关,其结果在物理和力学等领域中应用广泛.

关 键 词:某类微分系统  特征值(谱)  上界估计

Abstract:This paper considers estimates for eigenvalnes(spectrum) of a differential system. The inequality of the upper bound of the (n+1)th eigenvalue is estimated from the first n eigenvalues by using integral, Reyleigh theorem and inequality estimation. The estimate coefficients do not depend on the measure of the domain in which the problem is concerned . The result is widely used in physics and mechanics.
Keywords:a differential system  eigenvalue(spectrum)  weighted estimate
