Given two weights σ, w on R n , the classical g-function satisfies the norm inequality g(fσ) L 2 (w)f L 2 (σ) if and only if the two weight Muckenhoupt A 2 condition holds, and a family of testing conditions holds, namelyuniformly over all cubes I ⊂ R n , and Q(I) is the Carleson box over I.A corresponding characterization for the intrinsic square function of Wilson also holds.
