Asymptotics of $L^{r}$ extremal polynomials for $0 < r \leq \infty$ on $C^{1 +}$ Jordan regions

Benedikt Buchecker, Benjamin Eichinger, Maxim Zinchenko

We study strong asymptotics of $L^{r}$ -extremal polynomials for measures supported on Jordan regions with $C^{1 +}$ boundary for $0 < r < \infty$ . Using the results for $r = 2$ , we derive a…

Lower Bounds for Weighted Chebyshev and Orthogonal Polynomials

GÃ¶kalp Alpan, Maxim Zinchenko

We derive optimal asymptotic and non-asymptotic lower bounds on the Widom factors for weighted Chebyshev and orthogonal polynomials on compact subsets of the real line. In the Cheb…
