摘要：
We study the interval-valued fuzzy ideals of a semigroup S. For the sake of brevity, we simply call the interval-valued fuzzy ideals and the interval-valued fuzzy points as the (i-v) fuzzy ideals and the (i-v) fuzzy points, respectively. It is proved that if μ̃ is an (i-v) fuzzy ideal of a semigroup S, then μ̃ is an (i-v) prime fuzzy ideal of S if and only if μ̃c is an (i-v) fuzzy m-system of S. Some characterization theorems of the (i-v) prime fuzzy ideals and (i-v) completely prime fuzzy ideals of semigroup S are given. © 2013 Pleiades Publishing, Ltd.
