Abstract:

Let F be a family of meromorphic functions in the domain D , all of whose zeros are multiple. Let n   ( n ≥ 2 ) be an integer and let a , b be two nonzero finite complex numbers. If f + a ( f ' ) n and g + a ( g ' ) n share b in D for every pair of functions f , g ∈ F , then F is normal in D .
