与经典正交多项式相关的Dunkl-超对称正交函数

Dunkl-Supersymmetric Orthogonal functions associated with classical orthogonal polynomials

Yu Luo, Satoshi Tsujimoto, Luc Vinet, Alexei Zhedanov

摘要:

在超对称量子力学模型的背景下,我们考虑了Dunkl型微分算子(其中包含反射算子R)L = dx R + v(x),(v(-x)= -v(x))的特征值问题.借助于已知的精确可解位势,通过求解这一特征值问题,我们构造了几类满足一定正交关系的函数。我们称之为Dunkl-SUSY正交函数。这些函数可以用经典的正交多项式(COP)来表示。这些函数的关键特征是它们成对出现,即,Qn(x)和Qn(-x)都是L的本征函数。文中还给出了Dunkl-SUSY正交多项式的一般公式。

英文摘要:

We consider the eigenvalue problem associated with the Dunkl-type differential operator (in which the reflection operator R is involved) L = dx R + v(x), (v(-x) = -v(x)), in the context of supersymmetric quantum mechanical models. By solving this eigenvalue problem with the help of known exactly solvable potentials, we construct several classes of functions satisfying certain orthogonality relations. We call them the Dunkl-supersymmetric (Dunkl-SUSY) orthogonal functions. These functions can be expressed in terms of the classical orthogonal polynomials (COPs). The key feature of these functions is that they appear by pairs, i.e., Qn(x) and Qn(-x) are both the eigenfunctions of L. A general formulation of the Dunkl-SUSY orthogonal polynomials is also presented.
