Totik, Vilmos
The norm of minimal polynomials on several intervals. (English)
[J] J. Approx. Theory 163, No. 6, 738-746 (2011). ISSN 0021-9045

Author's abstract: Using works of F. Peherstorfer, we examine how close the $n$-th Chebyshev number for a set $E$ of finitely many intervals can get to the theoretical lower limit 2cap$(E)^n$.
