It is known [6], [14], [19] that if belongs to a class of k-tiling domains when translated by a lattice Λ, there exists a Riesz basis of exponentials for constructed using k translates of the dual lattice . In this paper, we give an explicit construction of the corresponding biorthogonal dual Riesz basis. We also extend the iterative reconstruction algorithm introduced in [11] to this setting.

在多平铺上寻找Riesz指数基础的对偶
众所周知[6],[14],[19] 当由晶格Λ转换时,属于k个平铺域的一类,存在一个Riesz基的指数使用对偶晶格的k平移构造。在本文中,我们给出了相应的双正交对偶Riesz基的显式构造。我们还将[11]中介绍的迭代重建算法扩展到该设置。
