左定与定型Sturm-Liouville问题间特征值不等式
Inequalities Among Eigenvalues Between Left-Definite and Definite Sturm-Liouville Problems
【摘要】 应用左定和定型Sturm-Liouville问题特征值的Prüfer角刻画,以及其特征值对边界和边值条件的单调依赖关系,本文建立了左定Sturm-Liouville与两个相关的定型Sturm-Liouville问题之间的特征值不等式关系.
【Abstract】 This paper establishes the inequalities among the eigenvalues between an left-definite and two associated definite Sturm-Liouville problems.The methods used here are based on the Prüfer angle characterizations of Sturm-Liouville problems,and the monotonous dependence of the eigenvalues of Sturm-Liouville problems on the boundary and boundary conditions.
