Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Metastability is a phenomenon that occurs in the dynamics of a multi-stable non-linear system subject to noise. It is characterized by the existence of multiple, well separated time scales. The talk will be focus on the metastable behavior of the dilute Curie-Weiss model, that is a Ising spin system on a Erdos-Renyi random graph with $N$ vertices and retention probability $p \in (0,1)$. Each spin interacts with a external field, while the interaction among neighbouring spin variables is assumed to be of the same strength. In particular, I will discuss bounds on the mean exit time from the metastable to the stable state and the spectral gap.
