On skew derivations as homomorphisms or anti-homomorphisms [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2016 Let \(R\) be a prime ring. An additive map \(\delta :R\to R\) is called a skew derivation on \(R\) if there exists an automorphism \(\phi\) of \(R\) such that \(\delta(xy)=\delta(x)y+\phi(x)\delta(y)\) for all \(x,y\in R\). The paper presents a single theorem, stated as follows: Let \(R\) be prime with center \(Z\), and let \(I\) be a nonzero ideal of \

Journal of Computer and System Sciences, 2012 The homomorphism problem for relational structures is an abstract way of formulating constraint satisfaction problems (CSP) and various problems in database theory. The decision version of the homomorphism problem received a lot of attention in literature; in particular, the way the graph-theoretical structure of the variables and constraints ...

FIXED POINTS AND CUT-HOMOMORPHISMS GENERATED BY ACTIONS OF A BE-ALGEBRA ON ITS SUBALGEBRA [PDF]
Journal of Algebraic SystemsThe concept of actions of a BE-algebra on its subalgebra is introduced and certain properties of these actions are derived. The notion of cut-homomorphisms is introduced in BE-algebras and proved that the class of all cut-homomorphisms forms an ordered ...

Lattice Homomorphisms Induced by Group Homomorphisms [PDF]
Proceedings 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 the Homomorphisms of the Lie Groups and
Abstract and Applied Analysis, 2013 We first construct all the homomorphisms from the Heisenberg group to the 3-sphere. Also, defining a topology on these homomorphisms, we regard the set of these homomorphisms as a topological space.

Images of formal matrices of elements of matrix groups over associative rings
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020 The paper substantiates the image by formal matrices of some elements of linear groups over associative rings by using the properties of redundant and fixed modules.

Weakly linear homomorphisms in skew boolean modules [PDF]
Journal of Hyperstructures, 2015 In this paper we introduce the notion of linear, weakly linear and strongly linear homomorphisms between two Skew Boolean modules and obtain various properties. We also introduce a scalar multiplication on the set of all weakly linear homomorphisms (wHom(

Duality for powerset coalgebras [PDF]
Logical Methods in Computer Science, 2022 Let CABA be the category of complete and atomic boolean algebras and complete boolean homomorphisms, and let CSL be the category of complete meet-semilattices and complete meet-homomorphisms. We show that the forgetful functor from CABA to CSL has a left

Some categorical aspects of BCH-algebras
International Journal of Mathematics and Mathematical Sciences, 2003 We show that the category BCH of BCH-algebras and BCH-homomorphisms is complete. We also show that it has coequalizers, kernel pairs, and an image factorization system. It is also proved that onto homomorphisms and coequalizers, and monomorphisms and one-

Lattices of homomorphisms [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1986 AbstractGiven a variety K of lattice-ordered algebras, A ∈ K is catalytic if for all B ∈ K, K(A, B) is a lattice for the pointwise order. The catalytic objects are determined for various varieties of distributive-lattice-ordered algebras. The characterisations obtained do not show an overall unity and exhibit diverse behaviour.
