摘要
In this paper, we prove the following result: Let f(z) be a transcendental entire function, Q(z) a parts per thousand cent 0 be a small function of f(z), and n a parts per thousand yen 2 be a positive integer. If f (n) (z) and (f (n) (z))' share Q(z) CM, then , where c is a nonzero constant. This result extends Lv's result from the case of polynomial to small entire function.
