我们考虑了一大类非光滑维集Σinℝn上的排斥势能,其被积函数度量了切点相互作用.能量的有限性对集合Σ有三种影响:排除所有(先验允许的)自交的拓扑效应,几何和测度论效应,提供Σ在合适的膜平面上的大投影,从而提供Σ在小球内的大维Hausdorff测度,直到一致控制的尺度.最后,正则化效应最终导致Morrey-Sobolev嵌入定理的几何变体:对任意指数q&GT,任何具有有限能量的可容许集合Σ;2M,实际上是切面以Hölder连续方式变化的AC1-流形,其最优Hölder指数μ=1−(2m)/q。此外,局部C_1,μ-图表示的块大小仅根据能量值从下一致地控制。
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.
