Density of near-extreme events [PDF]
Phys. Rev. Lett. vol. 98, pp. 140201 (2007), 2007 We provide a quantitative analysis of the phenomenon of crowding of near-extreme events by computing exactly the density of states (DOS) near the maximum of a set of independent and identically distributed random variables. We show that the mean DOS converges to three different limiting forms depending on whether the tail of the distribution of the ...
