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…

Chebyshev polynomials related to Jacobi weights
Jacob S. Christiansen, Olof Rubin
We investigate Chebyshev polynomials corresponding to Jacobi weights and determine monotonicity properties of their related Widom factors. This complements work by Bernstein from 1…

Extremal polynomials and polynomial preimages
Jacob S. Christiansen, Benjamin Eichinger, Olof Rubin
This article examines the asymptotic behavior of the Widom factors, denoted , for Chebyshev polynomials of finite unions of Jordan arcs. We prove that, in contrast t…
