Uniqueness Theorems for Meromorphic Functions That Share Three Sets

In this article, we deal with the problem of uniqueness of meromorphic functions that share three sets, and obtain one set S with 5 elements such that any two nonconstant meromorphic functions ? and g satisfying E(S, ?) = E(S, g), E({0}, ?) = E({0}, g) and E({∞}, ?) = E({∞}, g) must be identical.
