Representations of bornologies

open access: yesApplied General Topology, 2022
Bornologies abstract the properties of bounded sets of a metric space. But there are unbounded bornologies on a metric space like $\mathcal{P}(\RR)$ with the Euclidean metric.

Primitive orthogonal idempotents for R-trivial monoids [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We construct a recursive formula for a complete system of primitive orthogonal idempotents for any R-trivial monoid. This uses the newly proved equivalence between the notions of R-trivial monoid and weakly ordered monoid.

A Categorical Approach to Syntactic Monoids [PDF]

open access: yesLogical Methods in Computer Science, 2018
The syntactic monoid of a language is generalized to the level of a symmetric monoidal closed category $\mathcal D$. This allows for a uniform treatment of several notions of syntactic algebras known in the literature, including the syntactic monoids of ...

The Ring Homomorphisms of Matrix Rings over Skew Generalized Power Series Rings

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2021
Let  M_n (R_1 [[S_1,≤_1,ω_1]]) and M_n (R_2 [[S_2,≤_2,ω_2]]) be a matrix rings over skew generalized power series rings, where R_1,R_2 are commutative rings with an identity element, (S_1,≤_1 ),(S_2,≤_2 ) are strictly ordered monoids, ω_1:S_1→End(R_1 ),〖

Examples of Pomonoids of Full Transformations of a Poset

open access: yesScientific Journal of King Faisal University: Basic and Applied Sciences, 2022
In this research, the partially ordered monoid (simple pomonoid) full transformations of a poset O(X) is studied, and some related properties are examined.

Ordered Monoids and J-Trivial Monoids [PDF]

open access: yes, 2000
The aim of this paper is to give a new proof of the following result of Straubing and Thérien (which is also a consequence of a well-known result of I. Simon): Every J-trivial monoid is a quotient of an ordered monoid satisfying the identity x
