Content, Learning Outcome and Preconditions

Content

These lectures have for the purpose to show how the geometrical methods such as Hamiltonian and Lagrangian formalisms can be used for systematically reduced dynamical description of complex multi-scale physical systems on the example of magnetised plasmas.
Perturbative Lie-Transform dynamical reduction method, derivation of Ampere, Poisson and kinetic equation from the variational principle as well as derivation of conservation laws are presented.
One of the targets consists in bringing together continuous and discrete versions of variational dynamical description. As an example of numerical implementation it will be shown how that discretised form of dynamics can be implementated to the Particle-In-Cell Monte-Carlo simulations.

Learning Outcome

Students acquire
- knowledge of perturbative geometrical methods for construction of dynamical reduction procedure in multi-scaled dynamical system.
- advanced variational calculus and Noether methods for conservation laws derivation: in continuous and Monte-Carlo finite element discretisation form.

Courses and Schedule

Learning and Teaching Methods

The module consists of 2 hours of lectures each week, supplemented by a 2 hours exercise class every second week. In the lectures, the relevant models and theoretical principles for their analysis are introduced, and illustrative examples are worked out in detail. In the exercise classes, the students apply the methods to some specific examples and implement them using the python language

Module Exam

Description of exams and course work

The module examination is an oral exam (20 minutes). Students have to be able to state and derive basic mathematical properties of variational methods, in particular the derivation of equations of motion, invariants an action principle. They also should know how to apply the concept of mimetic finite differences and Finite Element Exterior Calculus to different models issued from plasma physics.

Exam Repetition

The exam may be repeated at the end of the semester.
