A note on the homomorphism theorem for hemirings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
The fundamental homomorphism theorem for rings is not generally applicable in hemiring theory. In this paper, we show that for the class of N-homomorphism of hemirings the fundamental theorem is valid.

Fidelity Preserved Data Hiding in Encrypted Images Based on Homomorphism and Matrix Embedding

open access: yesIEEE Access, 2020

Random Graph-Homomorphisms and Logarithmic Degree [PDF]

open access: yes, 2002
A graph homomorphism between two graphs is a map from the vertex set of one graph to the vertex set of the other graph, that maps edges to edges. In this note we study the range of a uniformly chosen homomorphism from a graph G to the infinite line Z. It

Lattice Homomorphisms Induced by Group Homomorphisms [PDF]

open access: yesProceedings of the American Mathematical Society, 1951
Introduction. By a lattice homorphism of a group G onto a group G' we mean a single-valued mapping sb of the lattice L(G) of subgroups of G onto the lattice L(G') of subgroups of G', which preserves all unions and intersections, that is, which is subject to the conditions 1. (U,S,)(k U= (S,(k), 2.

On skew derivations as homomorphisms or anti-homomorphisms [PDF]

open access: yesCommentationes Mathematicae Universitatis Carolinae, 2016
Let $R$ be a prime ring with center $Z$ and $I$ be a nonzero ideal of $R$. In this manuscript, we investigate the action of skew derivation $(\delta,\varphi)$ of $R$ which acts as a homomorphism or an anti-homomorphism on $I$. Moreover, we provide an example for semiprime case.

On Logics and Homomorphism Closure [PDF]

open access: yes2021 36th Annual ACM/IEEE Symposium on Logic in Computer Science (LICS), 2021
Predicate logic is the premier choice for specifying classes of relational structures. Homomorphisms are key to describing correspondences between relational structures. Questions concerning the interdependencies between these two means of characterizing (classes of) structures are of fundamental interest and can be highly non-trivial to answer.

Continuous Homomorphisms Defined on (Dense) Submonoids of Products of Topological Monoids

open access: yesAxioms, 2020
We study the factorization properties of continuous homomorphisms defined on a (dense) submonoid S of a Tychonoff product D = ∏ i ∈ I D i of topological or even topologized monoids.

K-algebras on quadripartitioned single valued neutrosophic sets [PDF]

open access: yesJournal of Fuzzy Extension and Applications, 2020
Quadripartitioned single valued neutrosophic (QSVN) set is a powerful structure where we have four components Truth-T, Falsity-F, Unknown-U and Contradiction-C.

Towards a directed homotopy type theory [PDF]

open access: yes, 2018
In this paper, we present a directed homotopy type theory for reasoning synthetically about (higher) categories, directed homotopy theory, and its applications to concurrency. We specify a new `homomorphism' type former for Martin-L\"of type theory which
