The Rahman Polynomials Are Bispectral
F. Alberto Grünbaum Department of Mathematics, University of California, Berkeley, CA 94720, USA
Abstract:
In a very recent paper, M. Rahman introduced a remarkable family of polynomials in two variables as the eigenfunctions of the transition matrix for a nontrivial Markov chain due to M. Hoare and M. Rahman. I indicate here that these polynomials are bispectral. This should be just one of the many remarkable properties enjoyed by these polynomials. For several challenges, including finding a general proof of some of the facts displayed here the reader should look at the last section of this paper.
Keywords:
bispectral property; multivariable polynomials; rings of commuting difference operators.
