摘要:
假设f为有限 级超越亚纯函数, 利用Nevanlinna的基本理论与方法, 在 且 的最大公因数 的条件下, 证明了复合差分函数 具有无穷多个零点; 并在 时, 证明了 的零点收敛指数为 .
Abstract:
Let f is hypothesized as a transcendental meromorphic function of finite order ?. By using the fundamental theory and method of Nevanlinna, it is proved that composition differences have infinity zero and if then the exponent of convergence of the zeros of is under the condition that and the greatest common divisor of .
