A two weight inequality for the fractional integral when p = n/α

Let Iα be the fractional integral operator defined as Given a weight w (resp. v), necessary and sufficient conditions are given for the existence of a non trivial weight v (resp. w) such that holds for any ball B such that ||vxB||∞ > 0. © 1984 American Mathematical Society.
