A classification of hull operators in archimedean lattice-ordered groups with unit [PDF]
Categories and General Algebraic Structures with Applications, 2020 The category, or class of algebras, in the title is denoted by $\bf W$. A hull operator (ho) in $\bf W$ is a reflection in the category consisting of $\bf W$ objects with only essential embeddings as morphisms.

The order of a group of even order [PDF]
Proceedings of the American Mathematical Society, 2007 We will give an estimation of the order of a group of even order by the order of the centralizer of an involution using the classification of finite simple groups.

On the order of a group of even order
Journal of Algebra, 2007 Let \(G\) be a group of even order with a unique conjugacy class of involutions. In the paper under review the authors provide an upper bound for the order of \(G\) in terms of the centralizer \(H=C_G(t)\) of an involution \(t\) in \(G\). As an application the authors provide examples of sporadic simple groups, the groups \(Ly\) and \(Th\), whose ...

The group of order preserving automorphisms of an ordered abelian group [PDF]
Proceedings of the American Mathematical Society, 1958 1. Representation of an automorphism group by a group of matrices. Whenever possible we shall represent automorphisms by matrices. This is a straightforward generalization of the classical case (for example, see Kurosh [3, p. 156]), and no proofs will be given.

Idempotent 2x2 matrices over linearly ordered abelian groups [PDF]
Categories and General Algebraic Structures with ApplicationsIn this paper we study multiplicative semigroups of $2\times 2$ matrices over a linearly ordered abelian group with an externally added bottom element. The multiplication of such a semigroup is defined by replacing addition and multiplication by join and

Hierarchical nanochannels based on rod-coil block copolymer for ion transport and energy conversion
Giant, 2021 Designable block copolymer (BCP) membranes are emerging for reverse electrodialysis to capture the salinity gradient energy between seawater and river water. However, present BCP based nanochannels are usually prepared from flexible blocks.
