Dynamical Systems Modeling and Analysis

Dynamical Systems Modeling and Analysis is a core methodology within Systems Science that uses mathematical formalisms, such as differential or difference equations, to represent how a system's state evolves over time. The primary goal is to understand and predict the system's behavior by identifying key features like equilibrium points (stable states), periodic orbits (cycles), and bifurcations (sudden changes in behavior), as well as determining whether the system is stable, oscillatory, or chaotic. This approach allows researchers to simulate complex phenomena, from population dynamics and climate change to neural networks and economic cycles, revealing the underlying rules that govern their temporal evolution.
