Differential Equations for Mathematical Physics

Academic Year 2023/2024 - Teacher: Orazio MUSCATO

Expected Learning Outcomes

1. Give the basic elements of the partial differential equations of mathematical physics.

2. Understanding of physical phenomena governed by partial differential equations; Construction of mathematical models: equations of the waves, heat, Laplace and Boltzmann equation.

3. Understanding of the different solution methods: why it has been proposed a solution method? What are some other alternative methods? Understanding how the analytical solutions obtained are interpreting the physical real situations (wellposedness of the models or paradoxes).

4. It will be privileged the undertsnding the physical part, the models and their analytical solution.

Learning Assessment

Learning Assessment Procedures

The final exam consists of an oral test during which the candidate demonstrates that he has assimilated the topics covered in the course (understanding, reasoning and the ability to build examples will be privileged).

Verification of learning can also be carried out electronically, should the conditions require it.
