This paper describes two isomorphic invariants for graph theory. One of them is the adjacent matrix, symmetric matrix, defined on given graph. We have shown that any given graphs having the dual congruent adjacent matrices must be isomorphism. Some properties about adjacent matrix are obtained in ...

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...

Graph isomorphism problem is one of fundamental problems in graph theory. Proposed an isomorphism testing algorithm based on Dijkstra algorithm for plan graphs, and described how to imply Dijkstra algorithm to process distance matrix rapidly. The core idea of the algorithm is take distance vector-matr...
Also we give an indication of the complexity of the first-order theory of graph models by showing that the second-order theory of first-order definable elements of a graph model is first-order expressable in the model. 展开 关键词: COMPACT OPERATOR WEAKLY COMPACT OPERATOR CONSTRUCTIVE ...

In this chapter, the isomorphism application in graph theory is discussed. Various types of the isomorphism such as the automorphism and the homomorphism are introduced. The theorems and hints to reject or accept the isomorphism of graphs are the next section. In the some sections, knowledge about...
