本文给出了达布变换在正交多项式意义下的一种新的解释,并找到了任意达布变换产生一组新的正交多项式的条件。本文还讨论了具有正交多项式特征函数的线性微分算子的达布变换与因式分解之间的关系。
We give a new interpretation of Darboux transforms in the context of orthogonal polynomials and find conditions in or-der for any Darboux transform to yield a new set of orthogonal polynomials. We also discuss connections between Darboux trans-forms and factorization of linear differential operators which have orthogonal polynomial eigenfunctions.
