Some estimates for meromorphic functions sharing four values
In this paper the term "meromorphic function" will mean a meromorphic function in C. We will use the standard notations of Nevanlinna theory : T(r, /), m{r, c, /), N(r, c, /), N(r, c, /), N k (r, c, /), N k (r, c, f) (ceCU{oo|, fe=l, 2, »0, and …
