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

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.

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.

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.

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.

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.

On the Order Sequence of a Group

open access: yesThe Electronic Journal of Combinatorics
This paper provides a bridge between two active areas of research, the spectrum (set of element orders) and the power graph of a finite group. The order sequence of a finite group $G$ is the list of orders of elements of the group, arranged in non-decreasing order.

On a Theorem on Ordered Groups [PDF]

open access: yesProceedings of the Glasgow Mathematical Association, 1958
The following work establishes a new proof of the theorem: Every archimedean ordered group is abelian. This theorem has been proved differently by many authors. It was first proved by O. Hölder [2]. A second proof has been given by H. Cartan [1]: he uses the topology which is naturally introduced in the group by its order.

Limits of principal components analysis for producing a common trait space: implications for inferring selection, contingency, and chance in evolution. [PDF]

open access: yesPLoS ONE, 2009
Comparing patterns of divergence among separate lineages or groups has posed an especially difficult challenge for biologists. Recently a new, conceptually simple methodology called the "ordered-axis plot" approach was introduced for the purpose of ...

Abelization of join spaces of affine transformations of ordered field with proximity

open access: yesApplied General Topology, 2005
Using groups of affine transformations of linearly ordered fields a certain construction of non-commutative join hypergroups is presented based on the criterion of reproducibility of semi-hypergroups which are determined by ordered semigroups. The aim of
