In this webinar, presented by Asher Yahalom, we describe how MHD can be formulated through a variational principle as a field theory. In particular, we will address the appropriate choice of variational variables that will minimize the computational load and allow us to obtain new analytical solution and better numerical schemes.
We will also show how the new action principles will allow us to derive new constants of motion using Noether’s theorem, some of them with a topological interpretation.
