Effect of a heterogeneous site size distribution on the branch size distribution of tree networks

摘要: In this study, we investigate how the heterogeneous site size distribution affects behavior of branch critical trees. By assuming a power-law, P(s) ∼ s−α, for distribution, find that exponent τ is smaller than tree when α < 3. When ≥ 3, = 1.5, which value δ(s − 1). We also 1.5 other P(s)’s with finite 〈s2〉. Based on our measurement, physical origin discrepancy between measured in real river networks and suggested. As an extension measure directory computer operating systems discuss effect heterogeneity supercritical tree.
