Flip Bifurcation
Let f:R×R->R be a one-parameter family of C^3 maps satisfying
f(0,0) =
(1)
[画像:[(partialf)/(partialx)]_(mu=0,x=0)] = -1
(2)
[画像:[(partial^3f)/(partialx^3)]_(mu=0,x=0)] < 0.
(4)
Then there are intervals (mu_1,0), (0,mu_2), and epsilon>0 such that
1. If mu in (0,mu_2), then f_mu(x) has one unstable fixed point and one stable orbit of period two for x in (-epsilon,epsilon), and
2. If mu in (mu_1,0), then f_mu(x) has a single stable fixed point for x in (-epsilon,epsilon).
This type of bifurcation is known as a flip bifurcation. An example of an equation displaying a flip bifurcation is
| f(x)=mu-x-x^2. |
