Picard values and normal families of meromorphic functions

  • Yan Xu (a1), Fengqin Wu (a1) and Liangwen Liao (a2)

Let f be a transcendental meromorphic function on the complex plane ℂ, let a be a non-zero finite complex number and let n and k be two positive integers. In this paper, we prove that if nk+1, then assumes each value b∈ℂ infinitely often. Also, the related normal criterion for families of meromorphic functions is given. Our results generalize the related results of Fang and Zalcman.
