Weighted inequalities for potential operators on differential forms. (English) Zbl 1193.47054
The author extends a weak-type, two-weight inequality for potential operators [see D. Cruz-Uribe and C. Pérez, “Two-weight, weak-type norm inequalities for fractional integrals, Calderón-Zygmund operators and commutators”, Indiana Univ. Math. J. 49, No. 2, 697–721 (2000; Zbl 1033.42009)] to differential forms defined on an open set in \(\mathbb{R}^{n}\), and also proves a strong-type two-weight inequality for the solutions of the nonhomogeneous \(A\)-harmonic equation [for the scalar case, see E. Sawyer and R. L. Wheeden, “Weighted inequalities for fractional integrals on Euclidean and homogeneous spaces”, Am. J. Math. 114, No. 4, 813–874 (1992; Zbl 0783.42011)].
