Advances in Mathematical Physics, 2016, vol. 2016, issue 1

Abstract: We define a Lie bracket on a certain set of local vector fields along a null curve in a 4‐dimensional semi‐Riemannian space form. This Lie bracket will be employed to study integrability properties of evolution equations for null curves in a pseudo‐Euclidean space. In particular, a geometric recursion operator generating infinitely many local symmetries for the null localized induction equation is provided.
