WebIn the mathematical field of graph theory, a graph homomorphism is a mapping between two graphs that respects their structure. More concretely, it is a function between the vertex sets of two graphs that maps adjacent vertices to adjacent vertices. WebAn isomorphism exists between two graphs G and H if: 1. Number of vertices of G = Number of vertices of H. 2. Number of edges of G = Number of edges of H. Please note that the above two points do ...

Homomorphism of Graphs: A graph Homomorphism is a mapping between two graphs that respects their structure, i.e., maps adjacent vertices of one graph to the …
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.
