Abstract |
|
We introduce a density condition which applies to subsets, E, of a bounded region Ω in the complex plane. If E satisfies this condition, then it is possible to construct a quasiconformal mapping F, of Ω, subject to the following conditions: F is extremal for its boundary values; F is conformal throughout Ω − E; F is not conformal on E. The construction makes essential use of the Hamilton-Reich-Strebel characterization of extremal quasiconformal maps. |
