Students learn the mathematical structures common to complex phenomena found with non-linearity, and acquire systematic thinking skills for getting an overview of these phenomena from a systematic perspective. Specifically, the course concentrates on interaction, which is a feature of nonlinear systems, and spontaneous self-organization based on it, while students also systematically learn mathematical methodology related to modeling and analysis. Students also apply this methodology to biological, human, and social self-organization to promote a universal understanding of these as systems.
The course focuses on interaction, a feature of nonlinear systems, and self-organization based on it, as well as systematically studying mathematical methodologies related to the modeling of complex natural phenomena and their analysis. Students thereby acquire the thinking skills to have an overview of phenomena from a systematic perspective.
