Learning Outcomes

Learning outcomes

This course is aiming at familiarizing the students with a variety of advanced subjects related to differential equations. Both classical and modern subjects are studied. After attending this course, the students should be able to: be familiar with a vast set of subjects related to differential equations, start researching on subjects regarding the qualitative theory of differential equations, and familiarize himself with the bibliography related to the subjects he was taught.

General Competences

Working independently. Team work. Production of new research ideas. Production of free, creative and inductive thinking. Search for, analysis and synthesis of data and information, with the use of the necessary technology. Develop critical thinking skills.
