摘要
利用自相似tile的相关结论,给出了其平方可积空间中的一组规范正交集L2(T);证明了数字集DR在严格积条件下,其相应的自相似tile的自复制tiling集与格tiling的同一性;通过引入紧集的概念,得到了一种研究自相似tile数字集的新方法.
An orthonormal set of L^2(T) is given by using the correlated result of the self-similar tile T. It is proved that the lattice tiling of a self-similar tile is also the self-replicating tiling, provided the digit set D has strictly product-form. A new method to study the self-similar tile digit sets is also obtained by introducing the concept of tight set.
