Dimensions of a class of high-dimensional homogeneous Moran sets and Moran class

A class of high-dimensional homogeneous Moran sets and Moran classes are introduced and some dimensional properties are studied. The Hausdorff dimension, modified lower box-counting dimension, lower and upper box-counting dimension, and packing dimension of high-dimensional homogeneous and partial homogeneous Cantor sets are determined. Moreover, a kind of fractal E is obtained, which is not regular but with the property Dimw(Ed)=dDimw(E), where w denotes any of the dimensions mentioned above.

Approximate self-similarity of a class of cookie-cutter-like sets

According to the bounded variation theory and the bounded distortion property of cookie-cutter-like (CCL) sets, the approximate self-similarity of cookie-cutter-like sets satisfying certain conditions is studied. Based on the mean value theorem, it is proved that a class of special cookie-cutter-like sets is approximately self-similar. The results obtained in this paper extend the corresponding results that have already existed. Biography: JIANG Dengying(1976–), female, Lecturer, research direction: applied mathematics.
