A dynamical system is the description of how a system evolves in time, under a fixed rule applied to a point in a state space. The branch studies the long-run behaviour of such systems, including their trajectories, stability, periodicity, and chaos, with applications across mathematics, physics, biology, chemistry, engineering, economics, history, and medicine.

Facts
Central QuestionGiven a fixed rule for how a system's state changes from moment to moment, what can be said about its long-run behaviour, stability, periodicity, or unpredictability? 1 Key DebateA fully deterministic dynamical system can still be practically unpredictable. Edward Lorenz summarized the tension this creates for the field: chaos is when the present determines the future but the approximate present does not approximately determine the future. 2 Classification
