On the Uniqueness of Meromorphic Functions That Share Two Sets

Abstract

Abstract Using the notion of weighted and truncated sharings of sets we deal with the problem of uniqueness of meromorphic functions sharing two sets and obtain five theorems which not only improve a recent result of Yi and Lü [Acta Math. Sci. Ser. B Engl. Ed. 24: 83–90, 2004], but also improve and supplement the results of Lin and Yi [Kyungpook Math. J. 43: 73–85, 2003], Yi [Acta Math. Sinica (Chin. Ser.) 45: 75–82, 2002].
