OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
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.
