Commutativity of flows of locally Lipschitz vector fields For a pair (f,g) of vector fields of class C 1 , it is well known that local commutativity of the flows of f and g is equivalent to the vanishing of the Lie bracket [f,g]. 12 We now prove the extension of this result to the locally Lipschitz case.
WebMar 1, 2024 · We prove a flow box theorem for smooth 2-dimensional slow-fast vector fields, providing a simple normal form that is obtained by smooth coordinate changes, without having to change the time. We introduce a notion of 2d slow-fast diffeomorphism, define the log-determinant integral and prove a normal form theorem similar to the flow … 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 …
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 ...
