单位圆内代数体函数关于重级的T半径

T-Radius of the Algebroidal Function Dealing with Multiple Values in the Unit Disc

应用Ahlfors覆盖曲面的方法和2个型函数,证明了代数体函数在单位圆内关于重级的T半径的存在性,并推广了代数体函数在复平面上关于T方向的相关结论.

Using the Ahlfors＇ theory of the covering surface and two type-functions, the author confirms the existence of a T-radius for an algebroidal function dealing with multiple values in the unit disc, and extends some results of the T-direction of the algebroidal function on the complex plane.
