Convex $L$-lattice subgroups in $L$-ordered groups [PDF]
In this paper, we have focused to study convex $L$-subgroups of an $L$-ordered group. First, we introduce the concept of a convex $L$-subgroup and a convex $L$-lattice subgroup of an $L$-ordered group and give some examples.

On Ordered Divisible Groups [PDF]
Introduction and remarks. In the theory of ?la-sets three main theorems stand out: that an na-set is universal for totally ordered sets of power not exceeding Ma, that any two n,-sets of power Ma are isomorphic and that na-sets of power Ma exist provided Ma is a regular cardinal number and Ea 0. Further, P. Erd6s, L. Gillman and M.

Ordered groups with greatest common divisors theory
An embedding (called a GCD theory) of partly ordered abelian group G into abelian l-group Γ is investigated such that any element of Γ is an infimum of a subset (possible non-finite) from G. It is proved that a GCD theory need not be unique.

Topological lattice-ordered groups [PDF]
Several types of hulls and completions of lattice ordered groups have been obtained by algebraic methods. In this paper is laid some groundwork for the application of topological and uniform-space concepts to the same end by setting forth those links—topological, algebraic and semantic— between a topological lattice ordered group H and a topologically ...

Fuzzy neighborhood structures on partially ordered groups
Ahsanullah (1988) showed the compatibility between group structures and I-fuzzy neighborhood systems. In this paper, we require not only that the I-fuzzy neighborhood systems be compatible with the group structures, but also compatible with the order ...

Green’s relations for 2 × 2 matrices over linearly ordered abelian groups [PDF]
We consider semigroups of 2 Ã 2 matrices over linearly ordered abelian groups with respect to multiplication, which is defined similarly to tropical algebra. We study Greenâs relations on such semigroups.

Hierarchically ordered porous silica materials (HSMs) with a micro/mesoporous structure were successfully prepared with the sol-gel method using dextran, dextran/CTAB, and CTAB as templates.

Groupoid Fell bundles for product systems over quasi-lattice ordered groups [PDF]
Consider a product system over the positive cone of a quasi-lattice ordered group. We construct a Fell bundle over an associated groupoid so that the cross-sectional algebra of the bundle is isomorphic to the Nica-Toeplitz algebra of the product system ...

LEFT-ORDERABLE COMPUTABLE GROUPS [PDF]
AbstractDowney and Kurtz asked whether every orderable computable group is classically isomorphic to a group with a computable ordering. By an order on a group, one might mean either a left-order or a bi-order. We answer their question for left-orderable groups by showing that there is a computable left-orderable group which is not classically ...

Patterns of non-administration of ordered doses of venous thromboembolism prophylaxis: implications for novel intervention strategies. [PDF]
Recent studies have documented high rates of non-administration of ordered venous thromboembolism (VTE) prophylaxis doses. Intervention strategies that target all patients have been effective, but prohibitively resource-intensive.
