After attending a recent talk at TTI about dimension reduction by Moses Charikar in which he mentioned the special role stable distributions play, I made a note to freshen up my own scattershot knowledge of facts about stable distributions. Of course, things got too busy and the the note ended up on my sub-list of to-do items that get infinitely postponed. However, I’ve been saved by a recent post to ArXiV by Svante Janson, who does all sorts of interesting work on these cool objects called graphons (the limits of infinite graph processes) :
We give some explicit calculations for stable distributions and convergence to them, mainly based on less explicit results in Feller (1971). The main purpose is to provide ourselves with easy reference to explicit formulas. (There are no new results.)
All (or at least most) of the facts I wanted in one place! Hooray!
He starts with infinitely divisible distributions (e.g. Gaussian, Poisson, Gamma) and then talks about -stable distributions and the uniqueness of the corresponding measures for (the case gives the Gaussian. I’m still reading it (bits at a time), but it’s great to have little surveys like this — broadens the mind, builds character, &c.
