By means of nearly Chebyshev polynomials for K, the modulus of continuity of the Green functions gℂ\K is estimated. Markov's constants of the corresponding set are evaluated. © Instytut Matematyczny PAN, 2012.EnglishGreen functionModulus of continuityNearly Chebyshev polynomialsArticle10.4064/ap106-0-91730-6272
