## Transcritical Bifurcation

Example 2: Consider the planar system x = px-x1, y = -y, (x,y)pR2, ppR [3]

For p <0, there is a stable node point O (0, 0) and a saddle A (p, 0), and for p = 0, there is a nonhyperbolic equilibrium point O (0, 0) (saddle-node point). For p >0, there is a

stable node point A (p, 0) and a saddle 0 (0, 0). It is easy to know that the stability of 0 and A at p = 0 have commuted. The bifurcation diagram is displayed in Figure 5.
