We investigate the convergence and the rate of convergence in $||·|L_p||$, 1 < p < ∞, of a bivariate interpolating (with respect to a sparse grid) trigonometric polynomial in the framework of Sobolev spaces of dominating mixed smoothness.

We continue our earlier investigations of radial subspaces of Besov and Lizorkin-Triebel spaces on $ℝ^d$. This time we study characterizations of these subspaces by differences.
