Null Frenet-Serret Dynamics
Riccardo Capovilla, Jemal Guven, Efrain Rojas
Abstract
We consider the Frenet-Serret geometry of null curves in a three and a four-dimensional Minkowski background. We develop a theory of deformations adapted to the Frenet-Serret frame. We exploit it to provide a Lagrangian description of the dynamics of geometric models for null curves.
