Velocity of stochastic processes in two dimensions
Published online by Cambridge University Press: 01 July 2016
Extract
A basic class of spatial stochastic processes is that in which the phenomenon spreads between static individuals with probability of ‘infection’ falling off with distance according to a contact distribution (Mollison (1972)). The following questions then arise:
(1) How does the velocity of spread depend on the contact distribution? In particular, for which contact distributions is it finite?
(2) Does the phenomenon spread at a steady velocity, or does it spread in jumps?
