OxTalks is Changing
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.
Particle systems and systemic risk
Systemic risk in the banking system is the risk that small losses and defaults can escalate through endogenous effects to cause an event affecting large parts of the financial sector. We will consider some simple particle system models for the interactions between banks and show how this leads to stochastic McKean-Vlasov equations describing the whole system. The systemic risk can be captured through a loss function and we will show that this can have unexpected behaviour in different models.
