Reeb foliation

Reeb foliation is a concept in differential topology and dynamical systems that arises in the study of contact manifolds. It is named after the mathematician Georges Reeb. In the context of contact geometry, a contact manifold \( (M, \alpha) \) consists of a manifold \( M \) equipped with a contact form \( \alpha \), which is a differential one-form that satisfies a certain non-degeneracy condition.
