Abstract

It is shown that for the pluripolar set K = {(z, ez): |z| ≤ 1} in ℂ2 there is a global Bernstein-Walsh inequality: If P is a polynomial of degree n on ℂ2 and |P| ≤ 1 on K, this inequality gives an upper bound for |P(z, w)| which grows like exp(1/2n2 log n). The result is used to obtain sharp estimates for |P(z, ez)|.
