Consider the system \[ \begin {aligned} \dot {x} &= \mu +x^2+y^2,\\ \dot {y} &= -y+x^2 \end {aligned} \]

  1. State the Center Manifold Theorem for rest points. Briefly explain its importance in bifurcation theory.
  2. Using an approximate center manifold, determine the nature of the bifurcation at the origin at \(\mu =0\).
