We study the normality of families of meromorphic functions concerning shared values. We consider whether a family of meromorphic functions F is normal in , if, for every pair of functions and in F, and share the value b, where a and b are two finite complex numbers such that , n is a positive integer. Some examples show that the conditions in our results are best possible.
