自仿射地毯投影的豪斯多夫维数

The Hausdorff dimension of the projections of self-affine carpets

Andrew Ferguson, Thomas Jordan, Pablo Shmerkin

摘要:

研究了一类自仿射地毯的正交投影,其中Bedford地毯和McMullen地毯是其特例。我们的主要结果是,如果$Λ$是这样的地毯,并且某些自然非理性条件成立,则$Λ$在非主方向上的每个正交投影都有豪斯多夫维数$\min(γ,1)$,其中$γ$是$Λ$的豪斯多夫维数.这推广了Peres和Shmerkin关于Cantor集和的一个结果。

英文摘要:

We study the orthogonal projections of a large class of self-affine carpets, which contains the carpets of Bedford and McMullen as special cases. Our main result is that if $Λ$ is such a carpet, and certain natural irrationality conditions hold, then every orthogonal projection of $Λ$ in a non-principal direction has Hausdorff dimension $\min(γ,1)$, where $γ$ is the Hausdorff dimension of $Λ$. This generalizes a recent result of Peres and Shmerkin on sums of Cantor sets.
