Besicovitch subsets of self-similar sets
Let be a self-similar set with similarities ratio and Hausdorff dimension , let be a probability vector. The Besicovitch-type subset of is defined as where is the indicator function of the set . Let and be a gauge function, then we prove in this paper:(i) If , then moreover both of and are finite positive;(ii) If is a positive probability vector other than , then the gauge functions can be partitioned as follows ...
