The aim of the course is to provide adequate knowledge and skills in the field of mathematical methods applied to physics, as a tool for the treatment and modeling of geophysical problems.
At the end of the course, the student will have acquired inductive and deductive reasoning skills, will be able to schematize a phenomenon in terms of physical quantities, will be able to critically deal with the studied subjects, set a problem and solve it with analytical methods, taking care of them, with due rigor, both mathematical and physical aspects. The student will apply the scientific method to the study of natural phenomena and will be able to critically evaluate analogies and differences between physical systems and the methodologies to be used. He will also be able to use the appropriate mathematical tools, with due rigor, in the modeling of geophysical problems.
