Two weight function norm inequalities for the Poisson integral

Two weight norm inequalities for fractional one-sided maximal and integral operators

In this paper, we give a generalization of Fefferman-Stein inequality for the fractional one-sided maximal operator: Z +∞ −∞ M α (f)(x) w(x) dx ≤ Ap Z +∞ −∞ |f(x)|M αp(w)(x) dx, where 0 < α < 1 and 1 < p < 1/α. We also obtain a substitute of dual theorem and weighted norm inequalities for the one-sided fractional integral I α .

Two-Weight Orlicz Type Integral Inequalities for the Maximal Operator

p A v = u  , (1) holds for t = ) t ( = ) t (   , but not if 1 = p . Also for each   < p 1 there exists a pair p A ) v , u (  so that (1) fails in the special case t = ) t ( = ) t (   [3, p. 395]. In these exceptional cases we have a weak type inequality. An excellent reference is the book by J.Garcia-Cuerva and J.L.Rubio de Francia [3]. We refer the reader interested in the current stat...

Weighted norm inequalities for singular integral operators

Weighted norm inequalities for integral transforms

Weighted (L, L) inequalities are studied for a variety of integral transforms of Fourier type. In particular, weighted norm inequalities for the Fourier, Hankel, and Jacobi transforms are derived from Calderón type rearrangement estimates. The obtained results keep their novelty even in the simplest cases of the studied transforms, the cosine and sine Fourier transforms. Sharpness of the condit...

Weighted Norm Inequalities for Maximally Modulated Singular Integral Operators

We present a framework that yields a variety of weighted and vector-valued estimates for maximally modulated Calderón-Zygmund singular (and maximal singular) integrals from a single a priori weak type unweighted estimate for the maximal modulations of such operators. We discuss two approaches, one based on the good-λ method of Coifman and Fefferman [CF] and an alternative method employing the s...
