对于型如P(z)=z^m(z-α)^n(z-b)^n的多项式,其中,参数α,b为互异非零复数,m,n为互素正整数,利用Nevanlinna值分布理论中有关分支量的结果以及对多项式重根的分析,讨论P(z)成为亚纯函数唯一性多项式的充分必要条件。
Let P(z)=z^m(z-α)^n(z-b)^n with parameters a,b as distinct non zero complex number and m, n as relatively prime positive integers, by means of the result related to branch-value in Nevanlinna's value distribution theory and analysis of polynomial's multiple wot, the sufficient and necessary condition of P(z) to be a uniqueness polynomial of meromorphic functions (UPM) was obtained.
