On a conjecture of Nevai
Notarangelo Incoronata (University of Basilicata, Computer Sciences and Economics, Department of Mathematics, Potenza, Italy)
It is shown that a conjecture concerning the derivatives of orthogonal
polynomials, proved by Nevai in 1990 for generalized Jacobi weights, holds
for doubling weights as well.
Keywords: Orthogonal polynomials, derivatives of orthogonal polynomials, doubling weights
