During Michaelmas Term, OxTalks will be moving to a new platform (full details are available on the Staff Gateway).
For now, continue using the current page and event submission process (freeze period dates to be advised).
If you have any questions, please contact halo@digital.ox.ac.uk
We will describe the scaling limit of the subcritical contact process in terms of a marked Poisson point process and a quasi-stationary distribution, and discuss the question of uniqueness of the QSD in this and other contexts. Based on joint works with E. Andjel, F. Ezanno and P. Groisman, with Aurelia Deshayes, and with F. Arrejoría and P. Groisman.
