We study a cyclic Lotka-Volterra model of N interacting species populating a d-dimensional lattice. In the realm of a Kirkwood approximation, a critical number of species Nc(d) above which the system… (More)

An exact expression for the mass distribution ρ(M, t) of the ballistic ag-gregation model in one dimension is derived in the long time regime. It is shown that it obeys scaling ρ(M, t) = t −4/3 F… (More)

The kinetics of annihilating random walks in one dimension, with the half-line x > 0 initially filled, is investigated. The survival probability of the nth particle from the interface exhibits… (More)

We investigate the age distribution function P(t ,t) in prototypical coarsening processes. Here P(t ,t) is the probability density that in a time interval (0,t) a given site was last crossed by an… (More)

Coarsening underlies numerous natural processes including phase separation, grain growth, soap bubbles, and species segregation. It is generally believed that coarsening systems exhibit dynamical… (More)
