Abstract : In this paper, we give some uniqueness theorems of nonconstant meromorphic functions of hyper-order less than one sharing partially three or four small periodic functions with their shifts. As an application, some sufficient conditions for periodicity of meromorphic functions are given.Our results improve and extend previous results of W. Lin, X. Lin and A. Wu \cite{LLW}.
Keywords : Meromorphic functions, sharing partially values, uniqueness theorems
