Abstract

Let ø be a piecewise continuous complex valued function on ℝ s , s ≥ 1, which is 2π-periodic in each coordinate direction. Given a “meshsize” h = 2π/N, N ≥ 1, let F := F h := h Z s ∩ [0, 2π) s and
$$S():={{S}_{h}}():=\left\{ \sum\limits_{j\in \text{F}}{{{a}_{j}}(.-j)\left| {{a}_{j}}\in \mathbb{C} \right.} \right\}$$
.
