SUMMARY

The discussion focuses on determining the stability of degenerate critical points using phase plane analysis. It emphasizes the importance of recognizing whether the problem is a perturbation of a linear system, referencing the Theorem of Ordinary Differential Equations (ODE) by Coddington and Levinson. The use of Maple software is suggested for visualizing the immediate environment of the equilibrium point to aid in analysis. Periodic solutions may arise in such scenarios, highlighting the complexity of stability analysis in dynamical systems.

How can you determine the stability of a critical point which is degenerate?

Phase plane analysis. You could have periodic solutions. It helps to know if your problem is a perturbation of a linear system (Th. of ODE: Coddington, Levinson).

So I should always grab Maple and stare at the ( immediate environment of the) equibrilium point?
