A model of new-product diffusion is proposed in which a site-percolation dynamics represents socially-driven diffusion … the empirical finding of a delayed ``take-off'' of a new product to a drift of the percolation dynamics from a non …

crash hazard rate in the Johansen-Ledoit-Sornette model of rational expectation bubbles. The model is based on a percolation … crash. This provides a formula to estimate the crash hazard rate by summation over percolation clusters above a minimum size … of a power $s^a$ (with $a>1$) of the cluster sizes $s$, similarly to a generalized percolation susceptibility.The power …

their very strong spatial clustering. The observed seismicity patterns seem to be compatible with a percolation process …). Percolation theory predicts 1.9 for 2D percolation clusters and 1.8 for the backbone of 3D percolation clusters. If the observed … gradual increase in multifractality is due to multifractality reaching a maximum prior to the major slip (percolation), this …

A parsimonious percolation model for stock market is proposed, of which the avalanche dynamics agree with the real …
