摘要:
A Poisson point process Psi in d-dimensional Euclidean space and in time is used to generate a birth-growth model: seeds are born randomly at locations x(i) in R-d at times t(i) is an element of [0, infinity). Once a seed is born, it begins to create a cell by growing radially in all directions with speed nu > 0. Points of Psi contained in such cells are discarded, that is, thinned. We study the asymptotic distribution of the number of seeds in a region, as the volume of the region tends to infinity. When d = 1, we establish conditions under which the evolution over time of the number of seeds in a region is approximated by a Wiener process. When d >= 1, we give conditions for asymptotic normality. Rates of convergence are given in all cases.
