Critical Hausdorff Measure for Higher-Dimensional Bedford-McMullen Subshifts
Hua Qiu, Qi Wang
Let be a diagonal expanding integer matrix with and at least two distinct diagonal entries, and let $X\subset\math…
Conformal Dimension of Measures and Quasisymmetric Dimension Reduction
Hua Qiu, Qi Wang
We prove that the conformal dimension of every locally finite Borel measure is either zero or infinite. The main ingredient is a quasisymmetric dimension-reduction theorem: every f…
The Hausdorff measure and uniform fibre conditions for Barański carpet
Hua Qiu, Qi Wang
For a self-affine carpet of Barański, we establish a dichotomy: $ \text{either }\quad 0<\mathcal{H}^{\dim_{\text{H}} K}(K)<+\infty \quad\text{ or } \quad\mathcal{H}^{\dim_{\tex…
Assouad and lower dimensions of graph-directed Bedford-McMullen carpets
Hua Qiu, Qi Wang, Shufang Wang
We calculate the Assouad and lower dimensions of graph-directed Bedford-McMullen carpets, which reflect the extreme local scaling laws of the sets, in contrasting with known result…
-spectra of box-like graph-directed self-affine measures: closed forms, with rotation
Hua Qiu, Qi Wang
We consider -spectra of planar graph-directed self-affine measures generated by diagonal or anti-diagonal matrices. Assuming the directed graph is strongly connected and the s…
