Asymptotics of Chebyshev Polynomials, III. Sets Saturating SzegŐ, Schiefermayr, and Totik--Widom Bounds
Jacob S. Christiansen, Barry Simon, Maxim Zinchenko
We determine which sets saturate the Szeg}o and Schiefermayr lower bounds on the norms of Chebyshev Polynomials. We also discuss sets that saturate the Totik--Widom upper bound.

Asymptotics of Chebyshev Polynomials, II. DCT Subsets of
Jacob S. Christiansen, Barry Simon, Peter Yuditskii +1
We prove Szegő-Widom asymptotics for the Chebyshev polynomials of a compact subset of which is regular for potential theory and obeys the Parreau-Widom and DCT conditi…
