Internal Direct Products and the Universal Property of Direct Product Groups

open access: yesFormalized Mathematics, 2023
Abstract This is a “quality of life” article concerning product groups, using the Mizar system [2], [4]. Like a Sonata, this article consists of three movements. The first act, the slowest of the three, builds the infrastructure necessary for the rest of the article.

Triangular Norm-Based Elements on Bounded Lattices

open access: yesAxioms, 2023
In this study, we introduce the notion of the T-irreducible element as a generalization of the notion of the meet-irreducible element in complete lattices. We derive some related properties of these elements and T-prime elements.

On Independent Domination in Direct Products

open access: yesGraphs and Combinatorics, 2022
In \cite{nr-1996} Nowakowski and Rall listed a series of conjectures involving several different graph products. In particular, they conjectured that $i(G\times H) \ge i(G)i(H)$ where $i(G)$ is the independent domination number of $G$ and $G\times H$ is the direct product of graphs $G$ and $H$.

Super Connected Direct Product of Graphs and Cycles

open access: yesAxioms, 2022
The topology of an interconnection network can be modeled by a graph G=(V(G),E(G)). The connectivity of graph G is a parameter used to measure the reliability of a corresponding network. The direct product is an important graph product. This paper mainly

One-sided principal ideals in the direct product of two semigroups [PDF]

open access: yes, 1993
summary:A necessary and sufficient condition is given for a) a principal left ideal $L(s,t)$ in $S\times T$ to be equal to the direct product of the corresponding principal left ideals $L(s)\times L(t)$, b) an $\Cal L$-class $L_{(s,t)}$ to be equal to ...

Direct product decompositions of bounded commutative residuated $\ell$-monoids [PDF]

open access: yes, 2008
summary:The notion of bounded commutative residuated $\ell $-monoid ($BCR$ $\ell $-monoid, in short) generalizes both the notions of $MV$-algebra and of $BL$-algebra. Let $\c A$ be a $BCR$ $\ell $-monoid; we denote by $\ell (\c A)$ the underlying lattice
