WebDec 13, 2024 · By the flow box theorem this makes sense, as there is no singularity of ∇ f on S −. By the graph property φ will be transverse to S + . By [ 3 , Thm. 1.2] there is a C 0 time label function t : N → [ τ , ∞ ] , of class C 1 as a function N × : = N ∖ W s → [ τ , ∞ ) , which assigns to each point p the time it takes to reach the ... 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 …

For a vector field X on a manifold M we have, at least locally and for short time, a flow ψ t of X. If X is regular at some point, we can find coordinates rectifying the vector field such that ∂ 1 = X. Then the representation of ψ t is just ( x 1 + t, …, x n). But the representation of the differential d ψ t: T p M → T ψ t ( p) M ...
