Obiettivi formativi 

KNOWLEDGE AND UNDERSTANDING
By the end of the course the student is expected to be familiar with fundamental ideas of nonlinear analysis, bifurcation theory
with applications in dynamical systems and PDEs.

CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING By the end of the course the student is expected to be able to apply methods and techniques of nonlinear analysis acquired to solve problems and exercises of medium difficulty. The exercises can also be proposed as easy theoretical results.

JUDGMENT AUTONOMY
By the end of the course the student is expected to be able to recognize and apply basic techniques of nonlinear analysys and also to recognize situations and problems in which these techniques can be used advantageously.

COMMUNICATIVE SKILLS
By the end of the course the student is expected to be able to express himself with proficient command of language and exposure security on the topics of the course.

LEARNING CAPACITY
By the end of the course the student is expected to be able to consult standard texts of nonlinear analysis and bifurcation theory.
