Summary: | Two necessary and sufficient conditions for the validity of the conjectureK0(h) =K1(h) are given, which are independent of the complex dilatations of extremal quasiconformal mappings, where K0(h) is the maximal conformal modulus dilatation of the boundary homeomorphismh, K1(h) is the maximal dilatation of extremal quasiconformal mappings that agree withh on the boundary. In addition, when the complex dilatation of an extremal quasiconformal mapping is known, the proof of the result simplifies Reich and Chen Jixiu-Chen Zhiguo’s result. |
