Robert D. Girse

International Journal of Mathematics and Mathematical Sciences, 1986, vol. 9, 1-3

Abstract:

It is shown that for every homomorphism ϕ of a graph G there exists a contraction θ ϕ on G ¯ , the complement of G , such that ϕ ( G ) ¯ = θ ϕ ( G ¯ ) if and only if G is a complete n -partite graph.
