Ia. Aliev et Ad. Gadzhiev, WEIGHTED ESTIMATES OF MULTIDIMENSIONAL SINGULAR-INTEGRALS GENERATED BY THE GENERALIZED SHIFT OPERATOR, Sbornik. Mathematics, 77(1), 1994, pp. 37-55
Sufficient conditions on weights are found that ensure that a multidim
ensional singular integral operator generated by the generalized shift
operator acts boundedly from one weighted L(p)-space into another. It
is shown that in some cases the conditions are sharp.
