Maximal Functions in Ergodic Theory
Let be a probability space, and a measure-preserving endomorphism of . The maximal function of a function is
The maximal function of f verifies a weak bound analogous to the Hardy–Littlewood maximal inequality:
that is a restatement of the maximal ergodic theorem.

Famous quotes containing the words functions and/or theory:
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconsciousto get rid of boundaries, not to create them.”
