The strongly non-degenerate manifold covering conjecture for missing digits sets

About 3 years old · traced to

Let n≥1n\geq 1 be an integer, let M⊂RnM\subset\mathbb{R}^n be a strongly non-degenerate analytic manifold, let p>2p>2 be an integer, and let D⊊{0,…,p−1}nD\subsetneq\{0,\dots,p-1\}^n be a choice of at least two digits. For δ>0\delta>0, let MδM^\delta be the δ\delta-neighbourhood of MM in Rn\mathbb{R}^n. Covering conjecture. The set (M∩Kp,D)δ(M\cap K_{p,D})^\delta can be covered by

≪(1δ)max⁡{0,dim⁡HKp,D−(n−dim⁡HM)}\ll \left(\frac{1}{\delta}\right)^{\max\{0,\dim_{\mathrm{H}} K_{p,D}-(n-\dim_{\mathrm{H}} M)\}}

many δ\delta-balls. Here Kp,DK_{p,D} is the missing digits set associated with the base pp and digit set DD. Strong non-degeneracy is introduced to exclude excessive intersections with affine subspaces. The text gives no resolution; when the exponent is zero, the conjecture predicts that M∩Kp,DM\cap K_{p,D} is finite.
