Graph Theory - Isomorphism - A graph can exist in different forms having the same number of vertices, edges, and also the same edge connectivity. Such graphs are called isomorphic graphs. Note that we label the graphs in this chapter mainly for the purpo
IsomorphismNetworkImage visualizationThe graph theory is being used for representation in networks and chemical atomic structures very frequently. However, these days, uncertainties are imposed on such networks. Isomorphism in generalized fuzzy graphs has been introduced here to capture the similarity of ...
假定两个简单图G和H是同构的,找到他们之间的同构映射可能并不容易,但一旦这样的映射 \theta 被找到,就很容易验证这样的映射确实是同构映射,因为我们仅仅需要验证对于图G中的 \left( \begin{matrix} n \\ 2 \\ \end{matrix} \right) 对顶点对uv, uv\in E(G) 当且仅当 \theta(u)\theta(v)\in E(...
In this lesson, we are going to learn about graphs and the basic concepts of graph theory. We will also look at what is meant by isomorphism and homomorphism in graphs with a few examples.Updated: 11/05/2024 Defining Graphs AgraphG is triplet consisting of a set of edges E(G), a se...

The rest of the paper is organized as follows: Section 2 describes the basic concepts of graph theory. In Section 3, the initial value rule and the definition of AMAVS of topological graphs are presented, and several examples are delivered to illustrate the detection of similar vertices. In ...

This was also the original context in which homomorphisms were studied (see e.g. [1,2]). But at several occasions the attention turned to combinatorial side thus displaying the emerging maturity of graph theory and (early) theoretical computer science. One should mention here pioneering works ...
simple graphs with the same numbers of vertices and edges, the problem of determining whether there exist correspondences between these vertices and edges such that there is an edge between two vertices in one graph if and only if there is an edge between the corresponding vertices in the other...
