Certain operations on interval-valued picture fuzzy graphs with application
International Journal of Mathematics for Industry, 2023 Graph theory has various applications in computer science, such as image segmentation, clustering, data mining, image capturing, and networking. Fuzzy graph (FG) theory has been widely adopted to handle uncertainty in graph-related problems.

J-coloring of graph operations [PDF]
Acta Universitatis Sapientiae, Informatica, 2019 Abstract A vertex v of a given graph is said to be in a rainbow neighbourhood of G if every color class of G consists of at least one vertex from the closed neighbourhood N[v]. A maximal proper coloring of a graph G is a J-coloring if and only if every vertex of G belongs to a rainbow neighbourhood of G.

Weak Total Resolvability In Graphs
Discussiones Mathematicae Graph Theory, 2016 A vertex v ∈ V (G) is said to distinguish two vertices x, y ∈ V (G) of a graph G if the distance from v to x is di erent from the distance from v to y.

A Multiplicative Version of Forgotten Topological Index [PDF]
Mathematics Interdisciplinary Research, 2019 In this paper, we present upper bounds for the multiplicative forgotten topological index of several graph operations such as sum, Cartesian product, corona product, composition, strong product, disjunction and symmetric difference in terms of the F ...

On Divided-Type Connectivity of Graphs
Entropy, 2023 The graph connectivity is a fundamental concept in graph theory. In particular, it plays a vital role in applications related to the modern interconnection graphs, e.g., it can be used to measure the vulnerability of the corresponding graph, and is an ...

Typing Graph-Manipulation Operations [PDF]
, 2002 We present a graph-based data model called GDM where database instances and database schemas are described by certain types of labeled graphs called instance graphs and schema graphs. For this data model we introduce two graph-manipulation operations, an addition and a deletion, that are based on pattern matching and can be represented in a graphical ...

Operations on Intuitionistic Fuzzy Graph Structures
Fuzzy Information and Engineering, 2016 An intuitionistic fuzzy graph structure (IFGS) is a generalization of an intuitionistic fuzzy graph. The concept of intuitionistic fuzzy graph structure is introduced and investigated in this paper.
