SEMITOPOLOGICAL BL-ALGEBRAS AND MV-ALGEBRAS.

In this paper, by considering the notion of upsets, for any element x of a BL-algebra L, we construct a topology Tx on L and show that L-algebras with this topology formes a semitopological BL-algebras. Then we obtain some of the topological aspects of this structure such as connectivity and compactness. Moreover, we introduced two kinds of semitopological MV-algebra by using two kinds of definition of MV-algebra and show that they are equivalent. [ABSTRACT FROM AUTHOR]
