摘要
亚纯函数的特征函数T(r)(0≤r<1),若在单位圆内满足lim—r→1log+T(r)log11-r=ρ,(0<ρ<+∞),则对任意取定的数λ和λ1(0<λ<λ1≤1),必定存在序列{Rn},使得limn→∞log+T(Rn)log11-Rn=ρ,(0<ρ<+∞),以及T(Rλn)≤1λλ1ρT(Rn(1+0(1))(n→∞),T(Rλ1h)≤1λ1ρ(1+log1λ1log1λ)T(Rn)(1+o(1))(n→∞).若在单位圆内还满足limr→1T(r)log11-r=∞,则对任意取定的数λ(0<λ<1),必定存在序列{Rn}.使得limn→∞T(Rn)log11-Rn=∞以及T(Rλn)≤1λρT(Rn)(1+o(1))(n→∞)
For the characteristic function T(r) of meromorphic function in unit circle,if lim r→1 log +T(r) log 11-r=ρ(0<ρ<+∞), then there is a sequence {R n}, and such that lim n→∞ log +T(R n) log 11-R n=ρ(0<ρ<+∞),T(R λ n)<1λλ 1 ρT(R n)(1+o(1)) (n→∞), and T(R λ 1 n)<1λ 1 ρ(1+ log 1λ 1/ log 1λ) T(R n)(1+o(1)) (n→∞). for any given number λ and λ 1 (0<λ<λ 1≤1). (2)If (1) and lim r→1T(r) log 11-r=∞ hold,then there is a sequence {R n} ,such that lim n→∞T(R n) log 11-R n=∞ and T(R λ n)<(1λ) ρT(R n)(1+o(1)) (n→∞). for any given number λ(0<λ<1).
