Abstract: Canards are solutions of singularly perturbed ODEs that organise the dynamics
in phase and parameter space.  In this talk, we explore two aspects of canard theory:
their applications in the life sciences and their ability to generate new phenomena.
More specifically, we will use canard theory to analyse a canonical model of the
electrical activity in a heart muscle cell.  We demonstrate that pathological heart
rhythms, called early afterdepolarisations, are canard-induced phenomena.  We use this
knowledge to explain the rich set of model behaviours, some of which have also been
observed in experiments.  Then, we explore a new class of canard-induced patterns in
reaction-diffusion PDEs which exhibit coexisting domains of mutually synchronised
oscillators and complementary domains of decoherent (asynchronous) oscillators.  

Note: This seminar will be recorded, including participant questions (participants only
