New Results on Ideals in MV-‎algebras‎

In the present paper, by considering the notion of ideals in MV-algebras, we study some kinds of ideals in MV-algebras and obtain some results on them. For example, we present definition of ultra ideal in MV-algebras, and we get some results on it. In fact, by definition of ultra ideals, we present new conditions to have prime ideals, positive implicative ideals and maximal ideals in MV-algebras.
