On unicity of meromorphic functions and their derivatives
\textit{V. H. An} and \textit{H. H. Khoai} [Ann. Univ. Sci. Budap. Rolando Eötvös, Sect. Comput. 47, 117--126 (2018; Zbl 1413.30122)] considered the uniqueness of meromorphic functions when the derivative of some power of meromorphic functions share a set of elements with counting multiplicities. The authors of the paper use the notion of weighted sharing of sets to extend the results of V. H. An and H. H. Khoai.
