    SUBSETS OF THE GENERAL SIERPINSKI CARPET WITH MIXED GROUP FREQUENCIES

    We consider a class of subsets of the general Sierpinski carpet which is characterized by insisting that the allowed digits in the expansion occur with prescribed mixing group frequencies, determine their Hausdorff dimensions and give the necessary and sufficient conditions for their corresponding Hausdorff measures to be positive and finite.

    INTERSECTIONS OF TRANSLATION OF A CLASS OF SIERPINSKI CARPETS

    Fractals01 Jun 2018

    For β(0,12), a middle-(12β) Sierpinski carpet Γβ is defined as the self-similar set generated by the iterated function system (IFS) {Fi}4i=1, where Fi:22 is defined by

    Fi(x,y)=β(x,y)t+(1β)Xi,i=1,,4.
    Here, Xi{0,1}×{0,1}. In this paper, for TΓβΓβ, we investigated the equivalent characterizations of the intersection Γβ(Γβ+T) being a generalized Moran set. Furthermore, under some conditions, we show that Γβ(Γβ+T) can be represented as a graph-directed set satisfying the open set condition (OSC), and then the Hausdorff dimension can be explicitly calculated.
