摘要

设[见 PDF 中的公式]和[见 PDF 中的公式]是两个非恒定的分形函数，且[见 PDF 中的公式]是一个正整数。如果[见 PDF 中的公式]和[见 PDF 中的公式]共享 1 CM（计算乘数），[见 PDF 中的公式]和[见 PDF 中的公式]共享[见 PDF 中的公式]IM（忽略乘数），并且[见 PDF 中的公式]，那么要么[见 PDF 中的公式]，要么[见 PDF 中的公式]，其中[见 PDF 中的公式]。作为应用，我们还研究了与移项和差分算子有关的分形函数的共值问题。

Meromorphic Functions Sharing Two Values

Let [see formula in PDF] and [see formula in PDF] be two nonconstant meromorphic functions, and [see formula in PDF] be a positive integer. If [see formula in PDF] and [see formula in PDF] share 1 CM (counting multiplicities), [see formula in PDF] and [see formula in PDF] share [see formula in PDF] IM (ignoring multiplicities), and [see formula in PDF], then either [see formula in PDF] or [see formula in PDF], where [see formula in PDF]. As an application, shared values problems of a meromorphic function related to its shifts and difference operators are also investigated.
