On zeros of hypergeometric polynomials

by Cimwanga, Norbert Mbuyi.

Abstract (Summary)
Our focus, in this thesis, is on zeros of hypergeometric polynomials. Several problems in various areas of science can be seen in terms of the search of zeros of functions; and this search can be reduced to finding the zeros of approximating polynomials, since under some conditions, functions can be approximated by polynomials. In this thesis, we consider the zeros of a specific polynomial, namely the hypergeometric polynomial. We review some work done on the zero location and the asymptotic zero distribution of Gauss hypergeometric polynomials with real parameters. We extend some contiguous relations of 2F1 functions, and then we deduce the zero location for some classes of Gauss polynomials with non-real parameters. We study the asymptotic zero distribution of some classes of 3F2 polynomials that extend results in the literature. 3
