特殊$X_m$ -Jacobi方程的谱分析

Spectral analysis for the exceptional $X_m$-Jacobi equation

Constanze Liaw, Lance Littlejohn, Jessica Stewart

摘要:

我们提供了$X_m$ -Jacobi谱理论的数学基础。也就是说,我们提出了一个自伴算子与特殊的$X_m$ -Jacobi正交多项式作为本征函数的微分表达式。这证明了这些多项式确实是自伴算子的本征函数(而不仅仅是形式本征函数)。进一步证明了在Lebesgue-希尔伯特空间中具有适当权的例外$X_m$ -Jacobi正交多项式($m, m+1, m+2, ...$次)的完备性.特别地,自伴算子没有其他谱。

英文摘要:

We provide the mathematical foundation for the $X_m$-Jacobi spectral theory. Namely, we present a self-adjoint operator associated to the differential expression with the exceptional $X_m$-Jacobi orthogonal polynomials as eigenfunctions. This proves that those polynomials are indeed eigenfunctions of the self-adjoint operator (rather than just formal eigenfunctions). Further, we prove the completeness of the exceptional $X_m$-Jacobi orthogonal polynomials (of degrees $m, m+1, m+2, ...$) in the Lebesgue--Hilbert space with the appropriate weight. In particular, the self-adjoint operator has no other spectrum.
