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...

A function [phi] : V(G) [right arrow] V(H) is a homomorphism from G to H if it preserves edges, that is, if for any edge [u, v] of G, [[phi](u), [phi](v)] is an edge of H [12]. Retractions and Homomorphisms on Some Operations of Graphs Define a homomorphism [[rho...
Although any isomorphism between two graphs is a homomorphism, the study of homomorphisms between graphs has quite a different flavour to the study of isomorphisms. In this chapter we support this claim by introducing a number of topics involving graph homomorphisms. We consider the relationship ...
GraphspolynomialsisomorphismThis paper initiates a general study of the connection between graph homomorphisms and the Tutte polynomial. This connection can be extended to other polynomial invariants of graphs related to the Tutte polynomial such as the transition, the circuit partition, the boundary, ...

It is clear from the definition of homomorphism that the identity map from || into || is an isomorphism of into iff (a) P is the restriction of P to ||, for each predicate parameter P; (b) f is the restriction of f to ||, for each function symbol f, and c = c for each ...
