Self-equivalence 3-rd order ODEs by time-¯xed transformations
Lie group Jet bundle Cartan equivalence problem Gardner method of moving frame
2009/1/4
Let y000 = f(x; y; y0; y00) be a 3-rd order ODE. By Cartan equiv-
alence method, we will study the local equivalence problem under the
transformations group of time-¯xed coordinates.
