Course objectives

The course is intended to provide the fundamentals of plasma physics. Starting from basic properties of plasmas, subjects address issues concerning single-particle dynamics and the microscopic statistical description of plasmas, which provide the basis for the formulation of kinetic and fluid theories. Applications of the theory to astrophysical plasmas and introduction to relativistic kinetic theory for plasmas subject to electromagnetic radiation-reaction are proposed.
