In this paper, we study the normality of a family of meromorphic functions and prove the following theorem: Let F be a family of meromorphic functions in a domain D , k , be two positive integers, and be a differential polynomial of f and . If the zeros of are of multiplicity and for each then F is normal in D . This result is related to a problem of Hayman [5].
