Abstract: Relations between $ L_u^p$ and $ H_u^p$ are studied for the product space $ {{\mathbf{R}}^1} \times {{\mathbf{R}}^1}$ in the case $ 1 < p < \infty$ and $ u({x_1},{x_2}) = \vert{Q_1}({x_1}){\vert^p}\vert{Q_2}({x_2}){\vert^p}w({x_1},{x_2})$, where $ {Q_1}$ and $ {Q_2}$ are polynomials and $ w$ satisfies the $ {A_p}$ condition for rectangles. A description of the distributions in $ H_u^p$ is given. Questions about boundary values and about the existence of dense subsets of smooth functions satisfying appropriate moment conditions are also considered.
