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

Applied 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

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

PLoS 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 ...

$\alpha$-Projectable and laterally $\alpha$-complete Archimedean lattice-ordered groups with weak unit via topology [PDF]

Categories and General Algebraic Structures with Applications
Let $\bf{W}$ be the category of Archimedean lattice-ordered groups with weak order unit, $\bf{Comp}$ the category of compact Hausdorff spaces, and $\mathbf{W} \xrightarrow{Y} \mathbf{Comp}$ the Yosida functor, which represents a $\bf{W}$-object $A$ as ...

c-Regular cyclically ordered groups [PDF]

, 2013
We define and we characterize regular and c-regular cyclically ordered abelian groups. We prove that every dense c-regular cyclically ordered abelian group is elementarily equivalent to some cyclically ordered group of unimodular complex numbers, that ...

Radical classes of l-groups

International Journal of Mathematics and Mathematical Sciences, 1994
The main results of this paper concern radical classes of l-groups. In the sections 2-3 the relationship between several radical classes of l-groups are discussed and the characteristic properties for several radical mappings are given. In the sections 5-

L-ordered and L-lattice ordered groups [PDF]

Information Sciences, 2015
This paper pursues an investigation on groups equipped with an $L$-ordered relation, where $L$ is a fixed complete complete Heyting algebra. First, by the concept of join and meet on an $L$-ordered set, the notion of an $L$-lattice is introduced and some related results are obtained. Then we applied them to define an $L$-lattice ordered group.

Monoids of O-type, subword reversing, and ordered groups [PDF]

, 2012
We describe a simple scheme for constructing finitely generated monoids in which left-divisibility is a linear ordering and for practically investigating these monoids.

Research Progress of Abrasive Groups Ordered Grinding Wheels

Chinese Journal of Mechanical Engineering
Because the grinding temperature is high when grinding using conventional disordered grinding wheels, the grinding quality improvement is limited when using single abrasive ordered grinding wheels, and the wheel preparation process is complex and costly ...
