A Molecular Shape Recognitive HPLC Stationary Phase Based on a Highly Ordered Amphiphilic Glutamide Molecular Gel

open access: yesNanomaterials, 2021
Chiral glutamide-derived lipids form self-assembled fibrous molecular gels that can be used as HPLC organic phases. In this study, HPLC separation efficiency was improved through the addition of branched amphiphilic glutamide lipids to the side chains of

Ordering groups and validity in lattice-ordered groups [PDF]

open access: yesJournal of Pure and Applied Algebra, 2019
A characterization is given of the subsets of a group that extend to the positive cone of a right order on the group and used to relate validity of equations in lattice-ordered groups (l-groups) to subsets of free groups that extend to positive cones of right orders.

Proof Theory and Ordered Groups

open access: yes, 2017
Ordering theorems, characterizing when partial orders of a group extend to total orders, are used to generate hypersequent calculi for varieties of lattice-ordered groups (l-groups).

Intuitionistic fuzzy lattice ordered G-modules [PDF]

open access: yesJournal of Fuzzy Extension and Applications
The investigation of mathematics underlines accuracy, precision, and flawlessness, yet in numerous genuine circumstances, individuals face equivocalness, ambiguity, imprecision, and so forth.

Word posets, with applications to Coxeter groups [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
We discuss the theory of certain partially ordered sets that capture the structure of commutation classes of words in monoids. As a first application, it follows readily that counting words in commutation classes is #P-complete.

Orderable 3-manifold groups [PDF]

open access: yesAnnales de l'Institut Fourier, 2005
We investigate the orderability properties of fundamental groups of 3-dimensional manifolds. Many 3-manifold groups support left-invariant orderings, including all compact P 2 -irreducible manifolds with positive first Betti number. For seven of the eight geometries (excluding hyperbolic) we are able to characterize which manifolds’ groups support a ...

Metric spaces related to Abelian groups

open access: yesApplied General Topology, 2021
When working with a metric space, we are dealing with the additive group (R, +). Replacing (R, +) with an Abelian group (G, ∗), offers a new structure of a metric space. We call it a G-metric space and the induced topology is called the G-metric topology.

Ordered groups as a tensor category

open access: yes, 2017
It is a classical theorem that the free product of ordered groups is orderable. In this note we show that, using a method of G. Bergman, an ordering of the free product can be constructed in a functorial manner, in the category of ordered groups and ...

Convex $L$-lattice subgroups in $L$-ordered groups [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2018
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 orderability of topological groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
A necessary and sufficient condition for a topological group whose topology can be induced by a total order compatible with the group structure is given and such groups are called ordered or orderable topological groups.
