鉴于Rs中的自相似集k,我们证明强烈的开放式条件和开放式条件既等同于HA(k)> 0,其中a是k和ha的相似性维度,表示该维度的Hausdorff度量。作为一个应用程序,我们显示了k具有内部点的情况,如果Ff是Lebesgue NULL集合。
Given a self-similar set K in Rs we prove that the strong open set condition and the open set condition are both equivalent to Ha (K) > 0, where a is the similarity dimension of K and Ha denotes the Hausdorff measure of this dimension. As an application we show for the case a = s that K possesses inner points iff it is not a Lebesgue null set.
