N2 - Let B be an exponential Blaschke product, let C be a compact subset of the unit disc 픻 with positive logarithmic capacity and let Kn = B−1(C) ∩ {z ∈ 픻: |z| ≤ 1 − 2−n}. We give a sharp estimate for the rate of growth of the capacity of the condensers (픻,Kn). Also, we examine a similar problem for universal covering maps of multiply connected Greenian domains and we give a precise formula in the case of doubly connected domains.
