Oxford Events, the new replacement for OxTalks, will launch on 16th March. The two-week OxTalks freeze period starts on Monday 2nd March. During this time, there will be no facility to publish or edit events. The existing OxTalks site will remain available to view during this period. Once Oxford Events launches, you will need a Halo login to submit events. Full details are available on the Staff Gateway.
I’ll start with a quick review on some classical results on exchangeability, particularly Kallenberg’s theorem on the canonical form of an exchangeable process on [0, 1]. The 2005 work of Aldous, Miermont and Pitman reveals a close connection between exchangeable processes and a class of continuum random tree called inhomogeneous continuum random trees (ICRT), leading to their claim that Lévy trees are mixtures of ICRT. I’ll present a proof in the case of stable Lévy trees, based upon a new way of constructing continuum random trees that work both for stable trees and ICRT.
