为有任意的矩阵膨胀的仿射的框架的一个足够的条件被介绍。它由史基于 univariate 格,并且与一个任意的实数从一种尺寸概括史, Casazza 和 Christensen 的 univariate 结果一(】 1 ) 膨胀到有任意的广泛的矩阵膨胀的更高的尺寸。
A sufficient condition for affine frame with an arbitrary matrix dilation is presented. It is based on the univariate case by Shi, and generalizes the univariate results of Shi, Casazza and Christensen from one dimension with an arbitrary real number a (a 〉 1) dilation to higher dimension with an arbitrary expansive matrix dilation.
