Separatrix

A phase curve (invariant Manifold) which meets a Hyperbolic Fixed Point (intersection of a stable and an unstable invariant Manifold). A separatrix marks a boundary between phase curveswith different properties. For example, the separatrix in the equation of motion for the pendulum occurs at the angular momentum where oscillation gives way to rotation.
