David, Guy Hausdorff dimension of uniformly non-flat sets with topology. (English) Zbl 1065.49028 Publ. Mat., Barc. 48, No. 1, 187-225 (2004). Let \(d\) be an integer, and let \(E\) be a nonempty closed subset of \(\mathbb{R}^n\). Assume that \(E\) is locally uniformly non-flat, in the sense that for \(x\in E\) and \(r> 0\) small, \(E\cap B(x,r)\) never stays \(\varepsilon_0r\)-close to an affine \(d\)-plane. Also suppose that \(E\) satisfies locally uniformly some appropriate \(d\)-dimensional topological nondegeneracy condition, like Semmes’ condition \(B\). Then the Hausdorff dimension of \(E\) is strictly larger than \(d\). It is seen that this as an application of uniform rectifiability results on Almgren quasiminimal (restricted) sets.
