| Abstract: |
| In this paper, we study the uniqueness of meromorphic functions sharing four small functions concerning the multiplicities. Using the precise form of the second fundamental theorem of Nevanlinna concerning small functions and the some technique of dealing with small functions, we improve some previous results. And also by the methods of handling shared pairs given by Gundersen, we further research the problems of meromorphic functions sharing five pairs of values or sharing four pairs of small functions, and obtain some results which extending and improving the related results. |
