The Order of Generalized Hypersubstitutions of Type τ=(2)
International Journal of Mathematics and Mathematical Sciences, 2008 The order of hypersubstitutions, all idempotent elements on the monoid of all hypersubstitutions of type τ=(2) were studied by K. Denecke and Sh. L. Wismath and all idempotent elements on the monoid of all hypersubstitutions of type τ=(2,2) were studied ...

Fundamental relation on m-idempotent hyperrings
, 2017 The γ*-relation defined on a general hyperring R is the smallest strongly regular relation such that the quotient R/γ* is a ring. In this note we consider a particular class of hyperrings, where we define a new equivalence, called εm∗ $\varepsilon^{*}_{m}

A Logratio Approach to the Analysis of Autosomal Genotype Frequencies Across Multiple Samples
Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT More than 25 years ago, Aitchison showed that the logratio principal component analysis of multiple samples of a biallelic polymorphism can evidentiate the Hardy–Weinberg law. However, hitherto compositional data analysis, that is, the logratio approach, has had little impact in population genetics.

Jurnal Sains Dasar, 2017 A complete idempotent semiring has a structure which is called a complete lattice. Because of the same structure as the complete lattice then inequality of the complete idempotent semiring can be solved a solution by using residuation theory.

Ideal based graph structures for commutative rings
Cubo, 2022 We introduce a graph structure $\gamrr$ for commutative rings with unity. We study some of the properties of the graph $\gamrr$. Also we study some parameters of $\gamrr$ and find rings for which $\gamrr$ is split.

P-partitions and a multi-parameter Klyachko idempotent [PDF]
, 2005 Because they play a role in our understanding of the symmetric group algebra, Lie idempotents have received considerable attention. The Klyachko idempotent has attracted interest from combinatorialists, partly because its definition involves the major ...

On maps sending rank-κ idempotents to idempotents
Operators and Matrices, 2019 Summary: We characterize bijective linear maps on complex-valued \(n\times n\) matrices such that rank-\( \kappa\) idempotents are mapped to idempotents, where \(2 \leqslant \kappa < n - 1\).

Radical preservation and the finitistic dimension
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We introduce the notion of radical preservation and prove that a radical‐preserving homomorphism of left artinian rings of finite projective dimension with superfluous kernel reflects the finiteness of the little finitistic, big finitistic, and global dimension.

Coideals, quantum subgroups and idempotent states [PDF]
, 2016 We establish a one to one correspondence between idempotent states on a locally compact quantum group G and integrable coideals in the von Neumann algebra of bounded measurable functions on G that are preserved by the scaling group. In particular we show

A complete closed-form solution to a tropical extremal problem [PDF]
, 2012 A multidimensional extremal problem in the idempotent algebra setting is considered which consists in minimizing a nonlinear functional defined on a finite-dimensional semimodule over an idempotent semifield.
