The following result is proved: if a bipartite graph is not a circle graph, then its complement is not a circle graph. The proof uses Naji’s characterization of circle graphs by means of a linear system of equations with unknowns in .
At the end of this short note I briefly recall the work of François Jaeger on circle graphs.
Nous prouvons le résultat suivant : si un graphe biparti n’est pas un graphe de cordes, alors son complément n’est pas un graphe de cordes. La preuve fait appel à une caractérisation des graphes de cordes par Naji, qui utilise un système d’équations linéaires sur le corps à deux éléments.
À la fin de cette note je rappelle brièvement le travail de François Jaeger sur les graphes de cordes.
