Zur Theorie der halbgeordneten Gruppen [PDF]

open access: yes, 1956
summary:The notion of a partially ordered partial abelian monoid is introduced and extensions of partially ordered abelian monoids by partially ordered abelian groups are studied. Conditions for the extensions to exist are found.

On left $C$-$\scr U$-liberal semigroups [PDF]

open access: yes, 2006
summary:In this paper the equivalence $\tilde{\mathcal Q}^U$ on a semigroup $S$ in terms of a set $U$ of idempotents in $S$ is defined. A semigroup $S$ is called a $\mathcal U$-liberal semigroup with $U$ as the set of projections and denoted by $S(

Classes of filters in generalizations of commutative fuzzy structures [PDF]

open access: yes, 2009
summary:Bounded commutative residuated lattice ordered monoids ($R\ell $-monoids) are a common generalization of $\mathit {BL}$-algebras and Heyting algebras, i.e. algebras of basic fuzzy logic and intuitionistic logic, respectively.
