👉 In mathematics, a "foliation" is a way to define and classify manifolds by using data about their topological structure. It's often used in topology to study the properties of certain topological spaces. A foliation can be defined on a manifold M (also known as a surface) as a collection of submanifolds, each of which is homeomorphic to another submanifold that is "finitely covered" by the others. This means that there are no more than
