Volume 31 • Number 1 • 2008   • Normal Families and Shared Values of Meromorphic Functions Chao Meng Abstract. Some criteria for determining the normality of the family F of meromorphic functions in the unit disc, which share values depending on f ∈ F with their derivatives is obtained. The new results in this paper improve some earlier related results given by Pang and Zalcman, Fang and Zalcman, A. P. Singh and A. Singh. 2000 Mathematics Subject Classification: 30D45, 30D35.
