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(

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.

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.

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-

Norm-attaining lattice homomorphisms [PDF]
, 2021 In this paper we study the structure of the set Hom(X,R) of all lattice homomorphisms from a Banach lattice X into R. Using the relation among lattice homomorphisms and disjoint families, we prove that the topological dual of the free Banach lattice FBL ...

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.

Mathematics, 2020 In this article, we investigate the fundamental properties of coalgebras with coalgebra comultiplications, counits, and coalgebra homomorphisms of coalgebras over a commutative ring R with identity 1R based on digital images with adjacency relations.

مجلة بغداد للعلوم, 2018 In this paper we study the notion of preradical on some subcategories of the category of semimodules and homomorphisms of semimodules. Since some of the known preradicals on modules fail to satisfy the conditions of preradicals, if the category of ...

Forum of Mathematics, PiAbstract We introduce new types of examples of bounded degree acyclic Borel graphs and study their combinatorial properties in the context of descriptive combinatorics, using a generalization of the determinacy method of Marks [Mar16]. The motivation for the construction comes from the adaptation of this method to the $\mathsf {LOCAL}$
