摘要

介绍了基于正交矩阵类的图样的双面谱，并讨论了它们的主要性质。特别是对图案的“镶嵌性”进行了研究。结果表明，尽管马赛克结构不能明确地确定，但图案的这种性质在光谱域中很容易被识别。然而，基于非阿贝尔群的二维狄利克雷核可以用于更有效的马赛克分析。

On Periodic Patterns and their Spectra

Two-sided spectra of patterns based on classes of orthogonal matrices are introduced and their main properties discussed. In particular, the “mosaicness” of patterns is studied. It is shown that this property of patterns may easily be recognized in the spectral domain, albeit the mosaic structure cannot be unambiguously determined. 2D-Dirichlet kernels based on non-Abelian groups can however be used for a more efficicient analysis of mosaics.
