Jianming Qi, Taiying Zhu
2010 Abstract and Applied Analysis  
LetFbe a family of meromorphic functions in the domainD, all of whose zeros are multiple. Letn (n≥2)be an integer and leta,bbe two nonzero finite complex numbers. Iff+a(f')nandg+a(g')nsharebinDfor every pair of functionsf,g∈F, thenFis normal inD.
