Abstract: Dually residuated lattice ordered monoids (\drl monoids) are common generalizations of, e.g., lattice ordered groups, Brouwerian algebras and algebras of logics behind fuzzy reasonings (\mv algebras, $BL$-algebras) and their non-commutative variants (\gmv algebras, pseudo $BL$-algebras). In the paper, lex-extensions and lex-ideals of \drl monoids (which need not be commutative or bounded) satisfying a certain natural condition are studied.
Keywords: \drl monoid, ideal, lex-extension, lex-ideal, algebras of fuzzy logics
