Some Basic Definitions of Graph Theory (1) : 네이버 블로그
Web121K views 8 years ago Graph Theory part-2 In this video I provide the definition of what it means for two graphs to be isomorphic. I illustrate this with two isomorphic graphs by giving an... In graph theory, an isomorphism of graphs G and H is a bijection between the vertex sets of G and H $${\displaystyle f\colon V(G)\to V(H)}$$such that any two vertices u and v of G are adjacent in G if and only if $${\displaystyle f(u)}$$ and $${\displaystyle f(v)}$$ are adjacent in H. This kind of bijection is … See more In the above definition, graphs are understood to be undirected non-labeled non-weighted graphs. However, the notion of isomorphic may be applied to all other variants of the notion of graph, by adding the requirements to … See more The Whitney graph isomorphism theorem, shown by Hassler Whitney, states that two connected graphs are isomorphic if and only if their See more • Graph homomorphism • Graph automorphism problem • Graph isomorphism problem • Graph canonization See more The formal notion of "isomorphism", e.g., of "graph isomorphism", captures the informal notion that some objects have "the same … See more While graph isomorphism may be studied in a classical mathematical way, as exemplified by the Whitney theorem, it is recognized that it is … See more 1. ^ Grohe, Martin (2024-11-01).
