Convexity of the zeros of some orthogonal polynomials and related functions

Jordaan, Kerstin Heidrun; Tookos, Ferenc (Elsevier, 2009)

We study convexity properties of the zeros of some special functions that follow from the convexity theorem of Sturm. We prove results on the intervals of convexity for the zeros of Laguerre, Jacobi and ultraspherical ...
