Normal Families of Meromorphic Functions Concerning Higher Derivative and Shared Values

Wei Chen, Wenjun Yuan, and Honggen Tian

Full-text: Open access


We study the normal families related to a Hayman conjecture of higher derivative and concerning shared values and get two normal criteria. Our results improve the related theorems which were obtained independently, respectively by Fang and Yuan (2001), Yuan et al. ((2011) and (2012)), Wang et al. (2011), and Qiu et al. (2012). Meanwhile, some examples are given to show the sharpness of our results.
