    Summary: For every homomorphism \(\phi\) of a graph G there exists a contraction \(\theta_{\phi}\) on \(\bar G,\) the complement of G. Here we study the graph equation \(\phi (G)=\theta_{\phi}(\bar G)\). In the course of our work we show that Hadwiger's Conjecture is true for every self- complementary graph.
