A well-known result of Arratia shows that one can make rigorous the notion
of starting an independent Brownian motion at every point of an arbitrary
closed subset of the real line and then building a set-valued process by
requiring particles to coalesce when they collide. Arratia noted that the
value of this process will be almost surely a locally finite set at all
positive times, and a...
