We consider repulsive potential energies, whose integrand measures tangent-point interactions, on a large class of non-smoothm-dimensional sets Σ in ℝn. Finiteness of the energyhas three sorts of effects for the set Σ: topological effects excluding all kinds of (a priori admissible) self-intersections, geometric and measure-theoretic effects, providing large projections of Σ onto suitablem-planes and therefore largem-dimensional Hausdorff measure of Σ within small balls up to a uniformly controlled scale, and finally, regularizing effects culminating in a geometric variant of the Morrey–Sobolev embedding theorem: Any admissible set Σ with finite-energy, for any exponentq>2m, is, in fact, aC1-manifold whose tangent planes vary in a Hölder continuous manner with the optimal Hölder exponentμ=1−(2m)/q. Moreover, the patch size of the localC1,μ-graph representations is uniformly controlled from below only in terms of the energy value.
