Learning outcomes

At the end of the course, the student has acquired competences on the mathematical tools of widest use in modeling energy systems, and more generally in treating problems in Physics. More specifically, the pupil is able to make us of: analytic functions; Fourier series; Fourier and Laplace integral transforms; PDE's. He/She will be acquainted with probability calculus: laws, random variables, main distributions and densities; including basic notions of statistics.
