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
Freidlin-Wentzell theory grants powerful tools to study the behaviour of dynamical systems perturbed by small noise. It applies naturally to ecological processes modelling large populations, as demographic noise scales as the inverse of the population size. This entails asymptotic estimates for the expected time to extinction, the typical path to extinction and the quasi-stationary distribution conditioned on non-extinction, formulated as large deviations results.
