摘要：

Suppose p(z) is a holomorphic function, the multiplicity of its zeros is at most d, P(z) is a nonconstant polynomial. Let ℱ be a family of meromorphic functions in a domain D, all of whose zeros and poles have multiplicity at least max{k2+d+1,k+d}. If for each pair of functions f and g in ℱ, P(f)f(k) and P(g)g(k) share a holomorphic function p(z), then ℱ is normal in D. It generalizes and extends the results of Jiang, Gao and Wu, Xu.
