A characterization of multiplier sequences for generalized Laguerre bases
arXiv:1210.7151
Abstract
We give a complete characterization of multiplier sequences for generalized Laguerre bases. We also apply our methods to give a short proof of the characterization of Hermite multiplier sequences achieved by Piotrowski.
