We present some classical differential models of Mathematical Physics, developing and analyzing analytical methods for the computation of the solutions.
Risultati di apprendimento attesi
The lectures and the laboratories will provide students with:
i) knowledge and understanding of (DD1) * the main properties of the solutions of some classes of linear partial differential equations; * the basic tools used for solving linear partial differential equations; * modeling of some physical problems
ii) the ability to apply the previous knowledge to simple examples on the calculator (DD2). In particular the student is required to * solve linear partial differential equations * discuss the properties of mathematical models
The instructor expects a broad comprehension of the subjects which sould not be limited to the statement of theoretical results. Instead, the acquired knowledge should enable students to express critical judgment and make informed choices on analytical methods for partial differential equations (DD3). The students are expected to express their answers in a mathematically rigorous and clear way.

Modalità di valutazione
There are five examination dates (two in January-February, two in June-July, one in September). The exam is written and consists in two questions on the theory (6 points each) and two exercises (10 points each). A positive evaluation requires at least 6 points on the theory, 10 points on the exercises and a total of 18 points.
