p-adic亚纯函数f 'P'(f),g 'P'(g)分担一个小函数

p-adic meromorphic functions f'P'(f), g'P'(g) sharing a small function

Kamal Boussaf, Escassut Alain, Jacqueline Ojeda

摘要:

设K是特征为零的完备代数闭p-adic域。设f,g是域K上的两个超越亚纯函数或开圆盘上的两个非有界解析函数的子函数的亚纯函数.设P是K或开圆上亚纯函数的唯一多项式,$α$是关于f和g的小亚纯函数.如果f 'P'(f)和g 'P'(g)共享$α$计数重数,则证明了f=g,条件是P'的零点的重数阶满足一定的不等式.如果$α$是Moebius函数或非零常数,我们可以得到关于P的更一般的结果。

英文摘要:

Let K be a complete algebraically closed p-adic field of characteristic zero. Let f, g be two transcendental meromorphic functions in the whole field K or meromorphic functions in an open disk that are not quotients of bounded analytic functions. Let P be a polynomial of uniqueness for meromorphic functions in K or in an open disk and let $α$ be a small meromorphic function with regards to f and g. If f'P'(f) and g'P'(g) share $α$ counting multiplicity, then we show that f=g provided that the multiplicity order of zeroes of P' satisfy certain inequalities. If $α$ is a Moebius function or a non-zero constant, we can obtain more general results on P.
