A Lattice-Theoretic Approach to Multigranulation Approximation Space [PDF]
The Scientific World Journal, 2014 In this paper, we mainly investigate the equivalence between multigranulation approximation space and single-granulation approximation space from the lattice-theoretic viewpoint.

Quadripartitioned single valued neutrosophic sets with covering based rough sets and their matrix representation [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 The notion of a quadripartitioned single-valued neutrosophic set (in short QSVNS) is considered to be the more general mathematical framework of the neutrosophic set to model indeterminacy.

Roughness of Filters in Equality Algebras
Bulletin of the Section of Logic, 2023 Rough set theory is an excellent mathematical tool for the analysis of a vague description of actions in decision problems. Now, in this paper by considering the notion of an equality algebra, the notion of the lower and the upper approximations are ...

THE IMPLEMENTATION OF A ROUGH SET OF PROJECTIVE MODULE
Barekeng, 2023 In ring and module theory, one concept is the projective module. A module is said to be projective if it is a direct sum of independent modules. (U, R) is an approximation space with non-empty set and equivalence relation If X subset U, we can form

Homomorphisms of Approximation Spaces [PDF]
Journal of Applied Mathematics, 2012 The notion of the homomorphism of approximation spaces is introduced. Some properties of homomorphism are investigated, and some characterizations of homomorphism are given. Furthermore, the notion of approximation subspace of approximation spaces is introduced. The relations between approximation subspaces and homomorphisms are studied.
