Learning objectives
The course, of an interdisciplinary nature within a mathematical context, aims among other things to deal with elements of Analytical Mechanics from an advanced point of view, and to provide methods useful to the search for exact solutions of differential equation systems, often related to problems of physical-mathematical interest.
