测量了开放、封闭和平坦空间中包装瑞士奶酪宇宙学的各种三维表示的多重分形谱，并确定空间的曲率不会改变相关的分形结构。将这些结果与大规模星系团聚的观测数据和模拟模型进行比较，以评估 PSC 作为此类结构形成的候选者的可行性。研究发现，PSC 尺寸光谱与观测结果不匹配，并提供了解决这种差异的可能解决方案，包括考虑潜在的光度偏差效应。还分析了各种随机和均匀集合，以深入了解多重分形谱的含义，因为它与观察到的缩放行为相关。
The multifractal spectrum of various three-dimensional representations of Packed Swiss Cheese cosmologies in open, closed, and flat spaces are measured, and it is determined that the curvature of the space does not alter the associated fractal structure. These results are compared to observational data and simulated models of large scale galaxy clustering, to assess the viability of the PSC as a candidate for such structure formation. It is found that the PSC dimension spectra do not match those of observation, and possible solutions to this discrepancy are offered, including accounting for potential luminosity biasing effects. Various random and uniform sets are also analyzed to provide insight into the meaning of the multifractal spectrum as it relates to the observed scaling behaviors.
