Asymptotic behavior of the Christoffel function related to a certain unbounded set

Part of the Lecture Notes in Mathematics book series (LNM,volume 1287)

Abstract

We study the asymptotic behavior, as the degree approaches infinity, of the Christoffel function at a fixed point z corresponding to a weight function of the type exp(−|z|λ) on the set |arg z|=π/2+α. The method generalizes that of Rakhmanov and also Mhaskar and Saff.
