关于正交多项式诱导的类代数的维数:非对称情形

On the dimensions of oscillator-like algebras induced by orthogonal polynomials: non-symmetric case

G. Honnouvo, K. Thirulogasanthar

摘要:

在实直线上,每一类正交多项式$\{Ψ_n(x)\}_{n=0}^{\infty}$都对应一个广义类代数,满足四项非对称递归关系$xΨ_n(x)=b_nΨ_{n+1}(x)+a_nΨ_n(x)+b_{n-1}Ψ_{n-1}(x),~Ψ_0(x)=1,~b_{-1}=0$。本文给出了关于$a_n$和$b_n$的有限维代数的充要条件。作为例子,我们讨论了与Laguerre多项式和Jacobi多项式相关的类代数的维数。

英文摘要:

There is a generalized oscillator-like algebra associated with every class of orthogonal polynomials $\{Ψ_n(x)\}_{n=0}^{\infty}$, on the real line, satisfying a four term non-symmetric recurrence relation $xΨ_n(x)=b_nΨ_{n+1}(x)+a_nΨ_n(x)+b_{n-1}Ψ_{n-1}(x),~Ψ_0(x)=1,~b_{-1}=0$. This note presents necessary and sufficient conditions on $a_n$ and $b_n$ for such algebras to be of finite dimension. As examples, we discuss the dimensions of oscillator-like algebras associated with Laguerre and Jacobi polynomials.
