Invariance refers to the property of a system or process that remains unchanged under certain transformations or conditions. This concept is crucial in understanding ergodic processes, where the statistical properties of a system are consistent over time, regardless of initial conditions or changes in the environment. Invariance helps in predicting long-term behavior and allows for simplifying complex problems by focusing on these stable characteristics.
congrats on reading the definition of Invariance. now let's actually learn it.
