Christoffel functions on Jordan curves with respect to measures with jump singularity
Tivadar Danka
In this paper we establish asymptotic results for Christoffel functions with respect to measures supported on Jordan curves having a Radon-Nikodym derivative with a jump singularit…

Christoffel functions with power type weights
Tivadar Danka, Vilmos Totik
Precise asymptotics for Christoffel functions are established for power type weights on unions of Jordan curves and arcs. The asymptotics involve the equilibrium measure of the sup…
