On Schwarz-Pick Inequality for Derivatives

关于导数Schwarz Pick引理 ,叙述了任何单位圆盘到其本身的解析函数 ,在双曲度量下是一个收缩

The Schwarz-Pick lemma states that any analytic functi on of the unit disc into itself is a contraction with respect to the hyperbolic In this note a correspending conclusion is proved for the derivative of analytic function
