Kinetic Plasma Lectures: Description of magnetic field lines without arcanes by dealing with the vector potential

D. F Escande
Aix-Marseille Université, CNRS

Topics:
* Stationary action principle for magnetic field lines
* Similarity of this principle and of that for Hamiltonian mechanics
* Each gauge of the vector potential provides a Hamiltonian for magnetic field lines
* Change of gauge and change of canonical coordinates are equivalent
* Calculations made easier with the action principle for magnetic field lines

Host: Gian Luca Delzanno
