universality of the percolation theory is still valid. In this study, the effect of power law size distribution on the critical …The standard percolation theory uses objects of the same size. Moreover, it has long been observed that the percolation … exponents of the percolation theory of the two dimensional models is investigated. Two different object shapes i.e., stick …

The problem of non-universality of the conductivity critical exponents in anisotropic percolating systems is discussed … in this paper. The authors bring simple arguments and gather experimental evidences to show that universality is … anisotropy. If the latter is constant within a non-vanishing region close to the percolation threshold, a single critical …
