Resumen:
For any CalderónZygmund operator T the following sharp estimate is obtained for 1 < p < : where . In the case where p = 2 and T is a classical convolution singular integral, this result is due to R. Fefferman and J. Pipher [7]. Then, we deduce the following weak type (1, 1) estimate related to a problem of Muckenhoupt and Wheeden [11]: where w A1 and (t) = t(1 + log+ t)(1 + log+ log+ t).
