The Poincare-Hardy inequality on the complement of the Cantor set E
$$\int {\frac{{\left| u \right|^2 }}{{dist^2 \left( {x,E} \right)}}dm \leqslant 4K^2 \cdot \int {\left| {\nabla u} \right|^2 dm} } $$
holds for every u 2 1 (R 3). Corresponding higher-order inequalities will be also derived. We use a special self-similar tiling and a natural metric on the space of trajectories generated by a Mauldin-Williams graph which is homeomorphic with the space of tiles endowed with the Euclidean distance. A crude estimation of the constant K is 2,100. Three applications will be briefly discussed. In the second one, the constant 1/2K -1 ≈ 0.0002 plays the role of an estimate for the dimensionless Planck constant in the corresponding uncertainty principle.
