We establish interior estimates for L p ‐norms, Orlicz norms, and mean oscillation of second derivatives of solutions to the Monge‐Ampère equation det D 2 u = f ( x ) with zero boundary value, where f ( x ) is strictly positive, bounded, and satisfies a VMO‐type condition. These estimates develop the regularity theory of the Monge‐Ampère equation in VMO‐type spaces. Our Orlicz estimates also sharpen Caffarelli's celebrated W 2, p ‐estimates. © 2008 Wiley Periodicals, Inc.
