Abstract:
In this paper, we study the uniqueness of meromorphic function and its differential polynomial sharing two small functions, and prove the follow theory. Let
f(z) be a nonconstant meromor-phic function satisfying
, let n be an integer and let
a(z) and
b(z) be two distinct small functions related to
f(z) . Let
, where
are small functions related to
f(z) . If
f(z) and
F(z) share
a(z) and
b(z) CM almost, then
.Thus, this result improves some existing results.
