Basic knowledge of algebra, geometry, real analysis in several variables, mechanics, electromagnetism
Solution of written exercises proposed by the teacher + oral exam
At the end of the course, the docent will propose some exercises to be solved at home. It will be evaluated as first the ability to frame the problem in the right context, the correctness of the procedure, the correctness of the mathematical passages and the ability to provide an answer to the problem.
It follows an oral discussion in order to evaluate the general theoretical knowledge of the student.
Acquisition of operational capabilities in the use of geometric instruments in the physical field.
At the end of the course the student will be able to:
-recognize the role of geometry in different physical models;
-provide examples;
-apply techniques of differential geometry to problems in physics;
-analyze a physical model from the geometric viewpoint;
-compare different geometric models in order to select the most suitable one;
-create new models
