โœฆ Synopsis


In this paper, we study the normality of a family of meromorphic functions concerning shared values and prove the following theorem: Let F F be a family of meromorphic functions in a domain D, let k G 2 be a positive integer, and let a, b, c be complex numbers such that a / b. If, for each f g F F, f and f ลฝ k . share a and ลฝ . b in D, and the zeros of f z y c are of multiplicity G k q 1, then F F is normal in D.
