Consider a large, finite collection of particles performing Brownian motion independently in space. We examine the process obtained by taking the minimum, at each time, of the distances of the particles, either (a) from the origin, or (b) from each other. In both cases, when time and space are suitably renormalized, we obtain a narrow convergence result. We also consider the number of pairs of particles which approach each other closely, over a unit time interval.
