| Abstract: | We derive estimates for Green and logarithmic potentials of measures associated with extremal points. These results are applied to obtain discrepancy estimates for weighted Fekete and Tsuji points on quasiconformal arcs or curves. September 21, 1998. Date revised: July 6, 1999. Date accepted: September 22, 1999. |
