Littlewood-Paley Operators on BMO
Littlewood-Paley Operators on BMO
Two Littlewood-Paley operators, the area integral and the function g^, are considered as operators on functions of bounded mean oscillation.It is proved that the image of a BMO function under one of these operators is either equal to infinity almost everywhere or is in BMO.
