Educational objectives
The student should acquire a basic knowledge of qualitative analysis of a Cauchy problem and of the theory necessary to deal with simple partial differential equations. The course matter is part of the contents of a standard reformed second level course for Italian master degrees in Geological Sciences. Even the setting is reformed, and the textbooks used are rich of examples and counterexamples, and therefore seem to be optimal to achieve a good understanding of the topics starting from exercises, that is from applications.Main knowledge acquired will be:
- To know the main topics of mathematical analysis and how to apply them to the earth sciences,
- To know the basilar theory of parabolic partial differential equations,
To know several tools to solve elementary and basilar exercises,
- To read and understand basilar texts of Mathematical Analysis,
- To work in teams, but also in autonomy.
The skills listed above are set out in the framework of the professions related to both a traditional Geologist, and a Geologist oriented to technical and/or industrial activities.Main competence (i.e. ability to apply the main knowledge acquired) will be:- To apply the theory to the resolution of exercises or problems based on models developed during lessons
- To analyze and treat simple qualitative problems in order to understand the appropriate second level analysis to perform,
- To solve some easy mathematical problems in the field of applied mathematics, indipendently.
To understand the topics covered in this course, the student should be familiar with all the contents of the courses Matematica (mod. 1 e mod. 2) included in the first level degree. In particular, a robust knowledge of the main definitions and elementary functions (polynomial functions, exponential function, logarithm and circular functions), a good knowledge in calculating limits and derivatives, and finally good knowledge of direct integrations, of integration of rational functions, of integration by parts and by substitution.
