Sturm-Liouville理论与正交函数

Sturm-Liouville Theory and Orthogonal Functions

H. Azad, M. T. Mustafa

摘要:

我们重温经典Sturm-Liouville理论的基础知识,作为应用,恢复Bochner的分类二阶常微分方程多项式系数和多项式的解决方案,由一个新的论点。我们还概述了如何更广泛的一类方程多项式的解决方案,可以通过允许的重量成为无限的孤立点:雅可比方程,在一般情况下,是这种类型。对于高阶方程,我们也给出了确定权函数和系数约束所需的基本分析,这些权函数和系数约束使方程定义的微分算子在偶数阶时自共轭,在奇数阶时反自共轭。我们也给出了明确的例子,这样的方程。

英文摘要:

We revisit basics of classical Sturm-Liouville theory and, as an application, recover Bochner's classification of second order ODEs with polynomial coefficients and polynomial solutions by a new argument. We also outline how a wider class of equations with polynomial solutions can be obtained by allowing the weight to become infinite at isolated points:the Jacobi equation, in general, is of this type. For higher order equations, we also give the basic analysis required for determining the weight functions and constraints on the coefficients which make the differential operator defined by the equation self adjoint for even orders and anti self adjoint in odd orders. We also give explicit examples of such equations.
