چکیده
2014 Exact expansions for susceptibility 2014 like mean perimeter series for directed percolation and extended mean size series are analysed, on two and three dimensional lattices. The critical threshold pc estimates are refined for the triangular and simple cubic lattices. On the square next-nearest-neighbour site problem pc is estimated as pc = 0.4965 ± 0.002. J.

The histogram characteristics of perimeter polynomials for directed percolation
2014 New perimeter polynomials (in dimensions d = 2 to 4) are analysed for directed site percolation. A study of these data shows that i) above pc the average perimeter-to-sizeratio varies as 03B1 = (1 2014 p)/p + Bs-1/d; ii) At pc its leading correction term estimates supports the prediction (from scaling) of an exponent equal to 1/0394 2014 1 (with 0394 the gap exponent for directed percolati...
متن کامل0 Statistics of lattice animals ( polyominoes ) and polygons
We have developed an improved algorithm that allows us to enumerate the number of site animals (polyominoes) on the square lattice up to size 46. Analysis of the resulting series yields an improved estimate, τ = 4.062570(8), for the growth constant of lattice animals and confirms to a very high degree of certainty that the generating function has a logarithmic divergence. We prove the bound τ >...
متن کاملDirected Animals, Quadratic Systems and Rewriting Systems
A directed animal is a percolation cluster in the directed site percolation model. The aim of this paper is to exhibit a strong relation between the problem of computing the generating function GF of directed animals on the square lattice, counted according to the area and the perimeter, and the problem of solving a system of quadratic equations involving unknown matrices. We present some solid...
متن کاملSite - bond percolation : a low - density series study of the uncorrelat ed limit
A generalisation of the pure site and pure bond percolation problems is studied, in which both the sites and bonds are independently occupied at random. This generalisa-tion-the site-bond problem-is of current interest because of its application to the phenomenon of polymer gelation. Motivated by considerations of cluster connectivity, we have defined two distinct models for site-bond percolati...
متن کاملScaling properties of the perimeter distribution for lattice animals, percolation and compact clusters
Scaling properties of the cluster distribution function and mean cluster size in the ensemble of clusters with fixed perimeter are analysed. The relevant scaling exponents are determined in all three regions of interest: lattice animals ( p < p c ) , percolation ( p = p , ) and compact clusters ( p > p c ) . Also, a form of the lattice animal distribution function in the statistical ensemble of...
