Chebyshev polynomials on a Jordan arc
Benedikt Buchecker, Benjamin Eichinger, Olof Rubin +1
We describe the asymptotics of Chebyshev polynomials on an analytic Jordan arc in the plane. This gives an affirmative answer to a conjecture of Christiansen-Simon-Zinchenko, based…

Weighted residual polynomials on a circular arc
Jacob S. Christiansen, Benjamin Eichinger, Olof Rubin +1
We study the behavior of weighted residual polynomials on circular arcs, including weighted Chebyshev polynomials. For weights given by reciprocals of polynomials, we establish Sze…

Asymptotics of extremal polynomials for on Jordan regions
Benedikt Buchecker, Benjamin Eichinger, Maxim Zinchenko
We study strong asymptotics of -extremal polynomials for measures supported on Jordan regions with boundary for . Using the results for , we derive a…
