A theory is presented in which much of the structure of spiral galaxies arises from a percolation phase transition that underlies the phenomenon of propagating star formation. According to this view, the appearance of spiral arms is a consequence of the differential rotation of the galaxy and the characteristic divergence of correlation lengths for ...

Let \({\mathbb Z}^3\) be the set of all 3-vectors \(x=(x_1,x_2,x_3)\) of integers and \({\mathbb L}=\{\{x,y\}\subset {\mathbb Z}^3: \|x-y\|=1\},\) where \(\|\cdot\|\) denotes Euclidean distance. Some definitions for finite and infinite entangled graphs in \({\mathbb L}\) are considered.

Hull percolation and standard percolation
Journal of Physics A: Mathematical and General, 1988The author shows that the 'hull percolation' problem considered recently by Roux et al. (1988) is in one-to-one correspondence with standard bond percolation. Their random tiling of the plane by squares with circles is identical with the Baxter-Kelland-Wu polygon decomposition associated with clusters of the Q-state Potts model, which in the Q to 1 ...

Confirmation of the fragmentation of percolation clusters at the percolation threshold
Physical Review B, 1993Comparison with early results concerning the dynamics of diffusion and invasion fronts allows one to confirm the fragmentation behavior of percolation clusters, in particular that λ=1 for the fragmenting ...

Suppose we immerse a large porous stone in a bucket of water. What is the probability that the centre of the stone is wetted? In formulating a simple stochastic model for such a situation, Broadbent and Hammersley (1957) gave birth to the ‘percolation model’. In two dimensions their model amounts to the following. Let ℤ2 be the plane square lattice and
