Learning outcomes

Mathematical tools necessary for the physics lectures and research work.

Goals

The objective of the course is to provide the student with the mathematical tools he will need to follow courses in theoretical physics and to carry on personal research works.

Content

The following mathematical tools are addressed

- Tensorial Algebra

- Vectorial Analysis

- The Dirac 'delta' function

- Linear response theory

- Group theory in physics and representation
