Abstract

In this paper, we introduce several types of subsets and of fuzzy sets of fully UP-semigroups, and investigate the algebraic properties of fuzzy sets under the operations of intersection and union.  Further, we discuss the relation between t-characteristic fuzzy sets and UPs-subalgebras (resp., UPi-subalgebras, UPs-filters, UPi-filters, UPs-ideals, UPi-ideals, strongly UPs-ideals and strongly UPi-ideals).
