Characterization of a two-weighted vector-valued inequality for fractional maximal operators.
A characterization of a two-weight inequality for discrete two-dimensional Hardy operators.
Weighted integral inequalities for maximal operators.
On the boundedness of classical operators on weighted Lorentz spaces.
A remark on Fefferman-Stein's inequalities.
It is proved that, for some reverse doubling weight functions, the related operator which appears in the Fefferman Stein's inequality can be taken smaller than those operators for which such an inequality is known to be true.
Weighted norm inequalities for maximal functions from the Muckenhoupt conditions.
For some pairs of weight functions u, v which satisfy the well-known Muckenhoupt conditions, we derive the boundedness of the maximal fractional operator M (0 ≤ s < n) from L to L with q < p.
On Muckenhoupt and Sawyer conditions for maximal operators.
Improved Muckenhoupt-Wheeden inequality and weighted inequalities for potential operators.
By a variant of the standard good λ inequality, we prove the Muckenhoupt-Wheeden inequality for measures which are not necessarily in the Muckenhoupt class. Moreover we can deal with a general potential operator, and consequently we obtain a suitable approach to the two weight inequality for such an operator when one of the weight functions satisfies a reverse doubling condition.
