Abstract

In this article, we prove that two admissible meromorphic functions and on an annulus must be linked by a Möbius transformation if they share a pair of values ignoring multiplicities and share other four pairs of values with multiplicities truncated by 2. We also show that two admissible meromorphic functions which share pairs of values ignoring multiplicities are linked by a Möbius transformation. Moreover, in our results, the zeros with multiplicities more than a certain number are not needed to be counted in the sharing pairs of values condition of meromorphic functions.
