On meromorphic functions that share one small function with their \(k\)th derivative. (English) Zbl 1198.30032

In this paper, the author studies the problem on meromorphic functions sharing a small function with their derivative. The proof heavily leans on the techniques of Nevanlinna theory. The result also improves some earlier results.
