We present a method of general applicability for finding exact values or accurate approximations of bond percolation thresholds for a wide class of lattices. To every lattice we systematically associate a polynomial, the root of which in [0, 1] is the conjectured critical point. The method makes the correct prediction for every exactly solved problem, and comparison with numerical results shows that it is very close, but not exact, for many others. We focus primarily on the Archimedean lattices… 

Polynomial sequences for bond percolation critical thresholds

In this paper, I compute the inhomogeneous (multi-probability) bond critical surfaces for the (4, 6, 12) and (34, 6) lattices using the linearity approximation described in Scullard and Ziff (2010 J.

The computation of bond percolation critical polynomials by the deletion–contraction algorithm

Although every exactly known bond percolation critical threshold is the root in [0,1] of a lattice-dependent polynomial, it has recently been shown that the notion of a critical polynomial can be

Transfer matrix computation of generalized critical polynomials in percolation

Percolation thresholds have recently been studied by means of a graph polynomial PB(p), henceforth referred to as the critical polynomial, that may be defined on any periodic lattice. The polynomial

Bond percolation thresholds on Archimedean lattices from critical polynomial roots

We present percolation thresholds calculated numerically with the eigenvalue formulation of the method of critical polynomials; developed in the last few years, it has already proven to be orders of

High-precision percolation thresholds and Potts-model critical manifolds from graph polynomials

The critical curves of the q-state Potts model can be determined exactly for regular two-dimensional lattices G that are of the three-terminal type. This comprises the square, triangular, hexagonal

Potts-model critical manifolds revisited

We compute critical polynomials for the q-state Potts model on the Archimedean lattices, using a parallel implementation of the algorithm of Jacobsen (2014 J. Phys. A: Math. Theor 47 135001) that

Critical manifold of the kagome-lattice Potts model

Any two-dimensional infinite regular lattice G can be produced by tiling the plane with a finite subgraph B⊆G; we call B a basis of G. We introduce a two-parameter graph polynomial PB(q, v) that

How Inhomogeneous Site Percolation Works on Bethe Lattices: Theory and Application

Using the above theory, the diffusion behaviour of an infectious disease (SARS) is discussed in detail and specific disease-control strategies in consideration of groups with different infection probabilities are presented.

Tight bounds for the bond percolation threshold of the (3, 122) lattice

Improved mathematically rigorous upper and lower bounds for the bond percolation threshold are established using the substitution method, in which stochastic ordering is checked using a network flow algorithm.

The results rule out the conjecture by Hsu and Huang that the bond thresholds are 2/3 and 1/3, respectively, but support the conjecture of Wierman that, for fully triangulated lattices other than the regular triangular lattice, the bond threshold is less than 2 sin pi/18 approximately 0.3473.

It is shown that symmetry, represented by a graph's automorphism group, can be used to greatly reduce the computational work for the substitution method, resulting in tighter bounds on the percolation threshold $p_c$.

Critical Percolation of Free Product of Groups

It is shown that the critical probabilities of the free product of these approximations converge to the critical probability of G1 * G2 * ⋯ * Gn and the speed of convergence is exponential, which means that for residually finite groups, for example, one can restrict oneself to the case when each free factor is finite.
