Homomorphisms between Fuzzy Approximation Spaces Based on Residuated Lattice
Journal of Applied Mathematics, 2014 Two kinds of homomorphisms of fuzzy approximation spaces based on complete residuated lattice are proposed. The homomorphisms are structure-preserving maps in some sense.

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.

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 $\mathsf {LOCAL}$

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 ...

Various Kinds of Freeness in the Categories of Krasner Hypermodules
International Journal of Analysis and Applications, 2018 The purpose of this paper is to study the concept of freeness in the categories of Krasner hypermodules over a Krasner hyperring. In this regards first we construct various kinds of categories of hypermodules based on various kinds of homomorphisms of ...

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.

The Homomorphism Theorems of M-Hazy Rings and Their Induced Fuzzifying Convexities
Mathematics, 2020 In traditional ring theory, homomorphisms play a vital role in studying the relation between two algebraic structures. Homomorphism is essential for group theory and ring theory, just as continuous functions are important for topology and rigid movements

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

Journal of Functional AnalysisWe introduce and study a notion of pureness for *-homomorphisms and, more generally, for cpc. order-zero maps. After providing several examples of pureness, such as "$\mathcal{Z}$-stable"-like maps, we focus on the question of when pure maps factor through a pure C*-algebra.

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(
