Groups, Graphs, Algorithms: The Graph Isomorphism Problem
Graph isomorphism is an equivalence relation on graphs and as such it partitions the class of all graphs into equivalence classes. A set of graphs isomorphic to each other is called an isomorphism class of graphs. See more 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 See more The formal notion of "isomorphism", e.g., of "graph isomorphism", captures the informal notion that some objects have "the same structure" if one ignores individual distinctions of "atomic" components of objects in question. Whenever … 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).

However, the notion of isomorphic may be applied to all other variants of the notion of graph, by adding the requirements to preserve the corresponding … See more The Whitney graph isomorphism theorem, shown by Hassler Whitney, states that two connected graphs are isomorphic if and only if their line graphs are isomorphic, with a single exception: … See more • Graph homomorphism • Graph automorphism problem • Graph isomorphism problem • Graph canonization See more Web图同构 (英語: graph isomorphism )描述的是 图论 中,两个 图 之间的 完全 等价关系。 在 图论 的观点下,两个同构的 图 被当作同一个图来研究。 目录 1 定义 1.1 一般定义 … dapr azure managed identity
