Flow box theorem
Webflow box: [noun] a mechanical reservoir that feeds beaten paper pulp onto the wire of a papermaking machine. WebThe flow box theorem ensures that for any point in the complement of the zero set w − 1 (0) there is a neighborhood U and a diffeomorphism Φ: U → [0,1] × D such that Φ ∗ w = ∂ z. Here D : = { x ∈ ℝ 2 : x ⩽ 1 } is the closed-unit 2-disk, and [ 0,1 ] × D is endowed with the natural Cartesian coordinates x ∈ D and z ∈ [ 0 ...

WebJan 1, 2014 · FormalPara Theorem 15.1. There exists a generic subset of the class of all smooth vector fields with an equilibrium manifold {x = 0} of codimension one. For every vector field in that class the following holds true: At every point (x = 0,y) the vector field is locally flow equivalent to an m-parameter family WebA generalization of the Flow-box Theorem is proven. The assumption of a C1 vector field f is relaxed to the condition that f be locally Lipschitz continuous. The theorem holds in any Banach space.
