Thus, concerning the critical pairs ([gamma], [sigma]) (the points of the critical region), we focus on the slope of the real part of the complex conjugate eigenvalues of the Jacobian as a function of [beta],inside an interval ([[beta].sub.cr]-[d.sub.1], [[beta].sub.cr] + [d.sub.2]), [d.sub.1], [d.sub.2] > 0 (where a pair of complex eigenvalues exist), in order to determine the direction and stability of the occurring codimension 1 Hopf bifurcation (see Appendix B).

Two large critical regions are said to be adjacent if they meet a common component [A.sub.0] of A, and are in the same component of [G.sub.f], joined by a sequence of edges and vertices where each vertex corresponds to a small critical region, each meeting [A.sub.0].
