Abstract: Let F  be a family of meromorphic functions in a domain DC,let k≥2 be a positive integer,and a,b,c,d be four finite complex numbers such that c≠0,d≠a,c≠b.If for every f∈F,all zeros of f-a have multiplicity at least k,and f(k)=b if and onl
y if f=a,and f =d whenever f(k)=c,then F is normal in  D.

Key words: meromorphic function, share value, normality
