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.

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-

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.

Distinguishing homomorphisms of infinite graphs [PDF]
, 2012 We supply an upper bound on the distinguishing chromatic number of certain infinite graphs satisfying an adjacency property. Distinguishing proper $n$-colourings are generalized to the new notion of distinguishing homomorphisms. We prove that if a graph $

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.

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 ...

SL2 homomorphic hash functions: Worst case to average case reduction and short collision search [PDF]
, 2015 We study homomorphic hash functions into SL(2,q), the 2x2 matrices with determinant 1 over the field with $q$ elements. Modulo a well supported number theoretic hypothesis, which holds in particular for concrete homomorphisms proposed thus far, we ...

Approximation of the multiplicatives on random multi-normed space
Journal of Inequalities and Applications, 2017 In this paper, we consider random multi-normed spaces introduced by Dales and Polyakov (Multi-Normed Spaces, 2012). Next, by the fixed point method, we approximate the multiplicatives on these spaces.

Exactness of Proximal Group Homomorphisms
Cumhuriyet Science Journal, 2022 This research introduces groups in proximity spaces which endowed with a proximity relation. Two penultimate choices for such relations are the Efremovic (EF) proximity relation and its extension, namely, the descriptive EF-proximity relation. There is a

Categorically closed topological groups
, 2017 Let $\mathcal C$ be a subcategory of the category of topologized semigroups and their partial continuous homomorphisms. An object $X$ of the category ${\mathcal C}$ is called ${\mathcal C}$-closed if for each morphism $f:X\to Y$ of the category ...
