摘要
It is shown that the d(n)th Chebyshev polynomials oil the Julia set J(P), and on the equipotential curve Gamma(P)(R), of the polynomial P(z) = z(d) - c, are identical and exactly equal to the nth iteration of P(z) itself. As an application, the capacity of the Julia set J(P) is deduced, a result that was first obtained by Brolin.
