Journal ArticleDOI
Rough approximation models via graphs based on neighborhood systems
TL;DR: This articleconstructs new types of eight neighborhoods for vertices of an arbitrary graph, say, j-adhesion neighborhoods, and investigates new kinds of j-lower approximations and j-upper approximation for any subgraph of a given graph.
Journal ArticleDOI
Certain types of coverings based rough sets with application
TL;DR: Using different neighborhoods, some different general topologies are generated as topologies induced from a binary relation and an interesting application of the new types of covering-based rough sets to the rheumatic fever is given.
Journal ArticleDOI
A model of a human heart via graph nano topological spaces
TL;DR: In this paper, new forms of nano topological spaces through a neighborhood system of vertices for a digraph will be presented and studied and will be definitely helpful to develop a tool in solving the blood flow system in the human heart.
Journal ArticleDOI
Some Topological Approaches for Generalized Rough Sets and Their Decision-Making Applications
TL;DR: New topological approaches are presented as a generalization of Pawlak’s theory by using j-adhesion neighborhoods and the relationship between them and some other types of approximations with the aid of examples are elucidated.
Journal ArticleDOI
Fuzzy topological structures via fuzzy graphs and their applications
TL;DR: In this paper, the authors introduce a new kind of fuzzy topological structures in terms of fuzzy graphs called fuzzy topology graphs due to a class of fuzzy subsets, and some of their properties are investigated.
