Résumé

Numerous dynamical systems are represented by a quadratic Hamiltonian with the phase space on the scrS2 sphere. In this paper, for the unique class of quadratic Hamiltonians depending on three parameters, we analyze the equilibria and the occurrence of parametric bifurcations; we obtain the surfaces of bifurcation in the space of parameters. We describe, in the context of quadratic Hamiltonians, a special type of bifurcation associated with a nonelementary fixed point; we name it a double teardrop bifurcation. © 1995 The American Physical Society.
