Ergodic theory examines the long-term statistical behavior of deterministic dynamical systems with invariant measures. It's essential for understanding the balance between predictability and randomness, with applications in physics, economics, and information theory. The Birkhoff Ergodic Theorem and concepts like ergodicity and recurrence are pivotal for predicting system behavior.
