Invariant properties for Wronskian type determinants of classical and classical discrete orthogonal polynomials under an involution of sets of positive integers

Guillermo P. Curbera, Antonio J. Duran

Given a finite set $F=\{f_1,\cdots ,f_k\}$ of nonnegative integers (written in increasing size) and a classical discrete family $(p_n{)}_n$ of orthogonal polynomials (Charlier, Meixn…
