WebTools. In mathematics, the Poincaré–Hopf theorem (also known as the Poincaré–Hopf index formula, Poincaré–Hopf index theorem, or Hopf index theorem) is an important theorem that is used in differential topology.

WebMar 28, 2024 · The Poincaré-Bendixson theorem goes as follows: Poincaré-Bendixson Theorem: Consider the equation $\dot {x} = f (x)$ in $\mathbb {R}^2$ and assume that $\gamma^+$ is a bounded, positive orbit and that $\omega (\gamma^+)$ contains ordinary points only. Then $\omega (\gamma^+)$ is a periodic orbit.
