The detailed topological or 'connectivity' properties of the clusters formed in diffusion limited aggregation (DLA) and cluster-cluster aggregation (CCA) are considered for spatial dimensions d=2, 3 and 4. Specifically, for both aggregation phenomena the authors calculate the fractal dimension d<sub>min</sub>= nu <sup>-1</sup> defined by l approximately R<sup>d(min)</sup> where l is the shortest path between two points separated by a Pythagorean distance R. For CCA, they find that d<sub>min</sub> increases monotonically with d, presumably tending toward a limiting value d<sub>min</sub>=2 at the upper critical dimensionality d<sub>c</sub> as found previously for lattice animals and percolation. For DLA, on the other hand, they find that d<sub>min</sub>=1 within the accuracy of the calculations for d=2, 3 and 4, suggesting the absence of an upper critical dimension. They also discuss some of the subtle features encountered in calculating d<sub>min</sub> for DLA. |
