Nonlinear research focuses on systems and phenomena that do not follow a linear relationship between cause and effect. These systems often exhibit complex behaviors, such as chaos, bifurcations, and self-organization. Nonlinear research spans a wide range of disciplines, including physics, biology, mathematics, and engineering. By studying nonlinear systems, researchers hope to gain a deeper understanding of the underlying principles that govern these complex behaviors and develop new tools and techniques for predicting and controlling them.
