半纯函数的Haymam方向

半纯函数的Haymam方向 HAYMAN DIRECTION OF A MEROMORPHIC FUNCTION 孙道椿 Sun Daochun first-author 设半纯函f（Z）的型函数为U（r）,若 T（r,f）/ln 3 r=∞则存在一个方向{arg z=0},对任意ε > 0及任意有限复数,a,b（b≠0）,有ln{n(r,f=a;|arg z-=b;|arg z-θ1 < ε}=1. Suppose that the type-function of the meromorphic function f（z） is U（r）. If T（r, f）/In 3 r=∞,then there exists a direction Δ（θ）, such that for any positive number ε and arbitorary finite complex nubers a, b（b≠0）, we have 1n{n（r, f=a; |arg z-θ| < ε）+n(r, f（k）=b; |arg z-θ| < ε} =1./1n U（r）-1n 1n r 国家教育委员会科基金 1986-03-01 2021-04-01 3
