They are quite well known several relationships between $A_p$ Muckenhoupt's weight functions and weighted inequalities for many singular integrals, like Riesz potentials, Riesz transforms, and the Hilbert trans-form. For instance it is a quite straightforward result of E. Stein that the weights for which all the Riesz Transformations are of weak type $(p,p)$ must be $A_p$ weights, or from the Helson-Szeg\"o you can deduce that the weights $w$ for which the Hilbert transform is bounded in $L^2(w)$ are $A2$-weights. In this presentation we give some conditions for pairs of weights involving two-weighted inequalities.
