WebKey words and phrases: distance sets, box dimension, Ahlfors regular sets, CP-processes 1 Introduction and main results In 1985, Falconer [4] (implicitly) conjectured that if A ˆRd, with d 2, is a Borel set of Hausdorff dimension at least d=2, then the set of distances dist(A;A)=fjx yj: x;y 2Ag has Hausdorff dimension 1.

Having identified some interesting random sets and possible ways to measure them, we note that such studies can be traced to the pioneering work of Lévy [30] and Taylor [47], [48], [49] on the sample path properties of the Brownian motion. We refer the reader to …
Web28 de ago. de 2024 · When we examine the random growth of trees along a linear alley in a rural area, we wonder what governs the location of those trees, and hence the distance between adjacent ones. The same question arises when we observe the growth of metal electro-deposition trees along a linear cathode in a rectangular film of solution.

Together with an earlier result of T. Orponen, this provides an improvement for the packing dimension of α -Furstenberg sets over the “trivial” estimate for all values of α ∈ (0, 1).
