Hopf bifurcation theorem
Consider a planar system of ordinary differential equations, written in such a form as to make explicit the dependence on a parameter : | | | | | | | | | |
Assume that this system has the origin as an equilibrium for all . Suppose that the linearization at zero has the two purely imaginary eigenvalues and when . If the real part of the eigenvalues verify | | |
and the origin is asymptotically stable at , then | | |
