ABSTRACT Let be a non-zero linear functional acting on the space of polynomials. Let be a Hahn operator acting on the dual space of polynomials. Suppose that there exist polynomials φ and ψ, with and , so that the functional equation holds, where the involved operations are defined in a distributional sense. In this note we state necessary and sufficient conditions, involving only the coefficients of φ and ψ, such that is regular, that is, there exists a sequence of orthogonal polynomials with respect to.

关于与哈恩算子相关的经典正交多项式

摘要设 是一个作用于多项式空间的非零线性函数。设一个作用于多项式对偶空间的哈恩算子。假设存在多项式 φ 和 ψ,具有 和 ,因此函数方程成立,其中涉及的运算是在分布意义上定义的。在这个注解中,我们陈述了充分必要条件,仅涉及 φ 和 ψ 的系数,这样是正则的,即存在关于 的正交多项式序列。
