On fuzzy
By means of a kind of new idea, we introduce the concepts of some kinds of fuzzy h-ideals in $$\Upgamma$$-hemirings. Some new characterization theorems of these kinds of fuzzy h-ideals of a $$\Upgamma$$-hemiring are also given. In particular, we show that the h-hemiregular $$\Upgamma$$-hemirings can be described by using these kinds of fuzzy h-ideals.
