In this paper, we study the quasisymmetric packing minimality of homogeneous perfect sets, and obtain that a special class of homogeneous perfect sets with $\operatorname{dim}_{P}E=1$ is quasisymmetrically packing minimal.
In literature it is shown that bi-Lipschitz maps between self-similar sets or self-affine sets enjoy a locally measure preserving property, namely, if $f:(E,μ)\to (F,ν)$ is a bi-Lipschitz map, then the Radon-Nykodym derivative $df^*ν/dμ$ is a constant function on a subset $E'\subset E$ with $μ(E')>0$, where $f^*ν(\cdot)=ν(f(\cdot))$. Indeed, this measure preserving property plays an important role in Lipschitz classification of fractal sets. In this paper, we show that such measure preserving property also holds for bi-Lipschitz maps between two Moran sets in a certain class.
We define the modulo-$m$ Toeplitz fixed point generated by Toeplitz substitution and study the lattice subsequence of such fixed point. Moreover, we provide a method to check whether one modulo-$m$ Toeplitz fixed point is a lattice subsequence of another.
