Cayley graphs under graph operations. II
2015Summary: The aim of this paper is to investigate the behavior of Cayley graphs under some graph operations. It is proved that the NEPS, corona, hierarchical, strong, skew and converse skew products of Cayley graphs are again Cayley graphs under some conditions.

Graph operations of Randic index
AIP Conference Proceedings, 2018The Randic index R(G) of a graph G whose vertex i and j has degree di and dj respectively is defined by sum of the 1/didj if the vertices i and j are adjacent. We introduce the weighted Randic index, we establish basic mathematical properties of Randic index and we investigate its behavior under some graph operations in this paper.

Graph Operations Decreasing Values of Degree-Based Graph Entropies
MATCH Communications in Mathematical and in Computer Chemistry, 2022The degree-based graph entropy Id is a parametric measure derived from an information functional defined by vertex degrees of a graph, which is used to characterize the structure of complex networks. Determining minimal values of Id is challenging due to a lack of effective methods to analyze properties of minimal graphs.

In this chapter, we define different ontological operations (such as similarity measurement and ontology graph based querying) that can be carried out with the use of generated Domain Ontology Graphs. These operations can be applied to develop various ontology based applications such as text classification, search engine, etc.

Among the many interesting problems of determining the proper connection numbers of graphs, it is worthwhile to study the proper connection number of G according to some constraints of the complementary graph.

Graph Operations and Free Graph Algebras
2018We introduce a concept of graph algebra that generalizes the traditional concept of algebra in the sense that (1) we use graphs rather than sets as carriers, and (2) we generalize algebraic operations to diagrammatic operations over graphs, which we call graph operations.

Predicting Graph Operator Output over Multiple Graphs
2019A growing list of domains, in the forefront of which are Web data and applications, are modeled by graph representations. In content-driven graph analytics, knowledge must be extracted from large numbers of available data graphs. As the number of datasets (a different type of volume) can reach immense sizes, a thorough evaluation of each input is ...
