  1. State the Center Manifold Theorem for rest points. Briefly explain its importance in bifurcation theory.
  2. Construct an approximation to the center manifold at the origin and use it to determine the local behavior of solutions. \[ \begin {aligned} \dot {x} &= -xy,\\ \dot {y} &= -y+x^2-2y^2. \end {aligned} \]
