Abstract: Weighted inequalities $\Vert f\Vert _{q,\nu,B_0}\le C\sum^{n}_{j=1}\Vert f_{xj}\Vert _{p,\omega_j,B_0}$ of Sobolev type $(\supp f\subset B_0)$ and of Poincaré type $(\bar f_{\nu,B_0}=0)$ are studied, with different weight functions for each partial derivative $f_{x_j}$ , for parallelepipeds $B_0\subset E_n, n\ge 1$ . Also, weighted inequalities $\Vert f\Vert _{q,\nu}\le C\Vert Xf\Vert _{p,\omega}$ of the same type are considered for vector fields $X=\{X_j\}$ , $j=1, \ldots, m$ , with infinitely differentiable coefficients satisfying the Hörmander condition.
