Weak prime \(\mathtt{L}\)--fuzzy filters of semilattices Weak prime \(\mathtt{L}\)--fuzzy filters of semilattices en en The concept of weak prime \(\mathtt{L}\)--fuzzy filter of a semilattice \(S\) is introduced and example are given. A characterization of weak prime \(\mathtt{L}\)--fuzzy filters is established and prime filters of \(S\) are identified with weak prime \(\mathtt{L}\)--fuzzy filters. Also, minimal weak prime \(\mathtt{L}\)--fuzzy filters are characterized. 1 9 Ch. Santhi Sundar Raj Department of Engineering Mathematics Andhra University India santhisundarraj@yahoo.com K.
