Objectives

LEARNING OUTCOMES:
Sound understanding and ability in the use of mathematical methods that are the foundation to courses of modern physics and to current research in all branches of physics, both at the theoretical and experimental level.

KNOWLEDGE AND UNDERSTANDING:
Understanding and mastery of advanced mathematical methods that are of use in other courses and in research contexts.

APPLYING KNOWLEDGE AND UNDERSTANDING:
Ability to prove theorems, derive mathematical properties, and make complex calculations. Moreover, ability to identify the areas of applicability of the mathematical methods proposed in class, especially for the resolution of complex problems, even when concerning new topics.

MAKING JUDGEMENTS:
Ability to integrate competences and assess autonomously the efficiency, adequacy, and correctness of the different mathematical methods in the resolution of problems concerning different fields in physics.

COMMUNICATION SKILLS:
Ability in clearly and correctly presenting the topics of the program. Additionally, ability to discuss the formulation, the hypotheses and the demonstration of theorems, and to communicate without ambiguity the logical steps and the conclusions of the analysis of a problem.

LEARNING SKILLS:
Capability of searching and integrating information present on different sources, like different textbooks and the WEB. It is also crucial the ability of elaborating and extending the examples and the applications presented in class.
