摘要
利用一类高阶微分方程组前几个特征值来估计第n+1个特征值的上界,其估计不依赖于区间长度。
This paper derives the imequality of eigenvalues for a class of higher differential equations.The upper bounds of the (n+1) the eigenvalue are shown by the front eigenvalues.This estimate do not depend on the measure of domain in which the problem is considered.
