Generalized Bi-ideal of Ordered Semigroup Related to Intuitionistic Fuzzy Point [PDF]
Intuitionistic fuzzy generalized bi-ideals play an important role in the study of ordered semigroups. In this paper, we try obtain more general form of intuitionistic fuzzy generalized bi-ideal of an ordered semigroup.

On categorical aspects of S -quantales
S-quantales are characterized as injective objects in the category of S-posets with respect to certain class of homomorphisms that are order-preserving mappings. This paper is devoted to exhibitions of categorical structures on S-quantales.

On Unitary down-closed regular monomorphisms of pomonoid actions [PDF]
In this paper we characterize injective objects in the category of S-posets and S-poset maps for a pomonoid S, with respect to the class of unitary down- closed embeddings.

On an equivalence between regular ordered Γ-semigroups and regular ordered semigroups
In this paper, we develop a technique which enables us to obtain several results from the theory of Γ-semigroups as logical implications of their semigroup theoretical analogues.

Quasi injectivity and θ-internal order sum in partially ordered acts [PDF]
Injectivity (weakly injectivity) of objects is an important concept which category theory inherited from homological and commutative algebra. One of the useful kinds of weakly injectivity is quasi injectivity. In this paper, we study the relation between

Fuzzy Quasi-Ideals of Ordered Semigroups [PDF]
. In this paper, we characterize ordered semigroups in terms of fuzzy quasi-ideals. We characterize left simple, right simple and completely regular ordered semigroups in terms of fuzzy quasi-ideals.

Some properties of residuated lattices [PDF]
We investigate some (universal algebraic) properties of residuated lattices -algebras which play the role of structures of truth values of various systems of fuzzy logic.

Fuzzy ideals of ordered semigroups with fuzzy orderings
The purpose of this paper is to introduce the notions of ∈, ∈ ∨qk-fuzzy ideals of a fuzzy ordered semigroup with the ordering being a fuzzy relation. Several characterizations of ∈, ∈ ∨qk-fuzzy left (resp. right) ideals and ∈, ∈ ∨qk-fuzzy interior ideals

P A ON (m, n)-IDEALS OF AN ORDERED SEMIGROUP [PDF]
: In this paper we introduce the concept of (m, n)-simple ordered semigroups extending the notion of simple ordered semigroups, and prove that an ordered semigroup (S, ·, ≤) does not contain proper (m, n)-ideals if and only if it is both (m, 0)-simple ...

HOMOTHETIC INTERVAL ORDERS [PDF]
We give a characterization of the non-empty binary relations  on a N∗-set A such that there exist two morphisms of N∗-sets u1, u2: A → R+ verifying u1 ≤ u2 and x  y ⇔ u1(x)>u2(y). They are called homothetic interval orders.
