Real zeros of 2F1 hypergeometric polynomials

Classical Analysis and ODEs 2013-01-31 v1

Abstract

We use a method based on the division algorithm to determine all the values of the real parameters bb and cc for which the hypergeometric polynomials 2F1(n,b;c;z)_2F_1(-n, b; c; z) have nn real, simple zeros. Furthermore, we use the quasi-orthogonality of Jacobi polynomials to determine the intervals on the real line where the zeros are located.
