论文摘要
考虑一个在实际线上的布朗颗粒系统，其中每对颗粒根据当地时间的交叉点以一定的速度聚结。假设系统中有许多初始粒子。我们给出了从无穷大的颗粒数量下降的必要条件。我们还确定了从Infinity的不同初始配置的速度。
Consider a system of Brownian particles on the real line where each pair of particles coalesces at a certain rate according to their intersection local time. Assume that there are infinitely many initial particles in the system. We give a necessary and sufficient condition for the number of particles to come down from infinity. We also identify the rate of this coming down from infinity for different initial configurations.
