Abstract:Let F be a family of mermorphic functions in a domain D, and let a, b, c be complex numbers, a ≠ b. If for each f ∈ F, the zeros of f - c are of multiplicity ≥ k 1,and E-f(k)(a) (∩)E-f(a), E-f(k)(b)(∩)Ef(b), then F is normal in D.
Keywords:Mermorphic functions  normal family  shared values
