Rough representations of rough topological groups

Applied General Topology, 2023
In this paper, the concept of rough representation of a rough topological group on a Banach space is explored. Mainly, the continuity and the irreducibility of rough representations are studied.

Rough U-Exact Sequence of Rough Groups

Al-Jabar, 2022
The notion of a U-exact sequence is a generalization of the exact sequence. In this paper, we introduce a rough U-exact sequence in a rough group in an approximation space.

Rough action on topological rough groups

Applied General Topology, 2020
In this paper we explore the interrelations between rough set theory and group theory. To this end, we first define a topological rough group homomorphism and its kernel.

THE PROPERTIES OF ROUGH V-COEXACT SEQUENCE IN ROUGH GROUP

Barekeng, 2022
In ring and module theory, the concept of an exact sequence is commonly employed. The exact sequence is generalized into the U-exact sequence and the V-coexact sequence.

Rough soft sets and rough soft groups [PDF]

Journal of Hyperstructures, 2013
In this paper we discuss some basic properties of rough soft sets and hence we introduce the notion of rough soft group. Basic properties of rough soft group are presented and supported by some illustrative examples.

Topological Rough Groups

Topological Algebra and its Applications, 2016
The concept of topological group is a simple combination of the concepts of abstract group and topological space. The purpose of this paper is to combine the concepts of topological space and rough groups; called topological rough groups on an ...

Sub-exact sequence of rough groups

Al-Jabar, 2021
Rough Set Theory (RST) is an essential mathematical tool to deal with imprecise, inconsistent, incomplete information and knowledge Rough Some algebra structures, such as groups, rings, and modules, have been presented on rough set theory.

The Homomorphisms and Operations of Rough Groups [PDF]

The Scientific World Journal, 2014
Based on the light relation between a normal subgroup and a complete congruence relation of a group, we consider the homomorphism problem of rough groups and rough quotient groups and investigate their operational properties.

Assessment of patient satisfaction with the hemodialysis experience using an integrated decision-making approach with rough numbers [PDF]

Scientific Reports
Patient satisfaction is a critical dimension of healthcare quality and hospital management, particularly in chronic treatments such as hemodialysis, where patients undergo frequent and time-intensive procedures.
