摘要
研究实轴R1上的保向同胚映照到上半平面Beurling Ahlfors延拓的伸张函数的性质 .通过证明几个不等式 ,对伸张函数D(z)作进一步的估计 ,改进了相关的结果 .
With regard to Beurling-Ahlfors extension from sense-preserving homeomorphism on real axis R 1 to the upper half plane, the authors make a study on the properties of its dilatation function; and form a further estimate of dilatation function D(z) through proving several inequalities by which some known results are improved.
