Name Title Date Time Room
Andrey Shilnikov (Georgia State University)Torus bifurcation in neuroscience modelsAbstract: We discuss several models, phenomenological and biologically plausible, that undergo a torus bifurcation and torus breakdown at the transition between neural activity types.

Sanjeeva Balasuriya (University of Adelaide)Stochastic sensitivity: a computable measure for uncertainty of deterministic trajectoriesAbstract: Uncertainties in velocity data are often ignored when computing Lagrangian particle trajectories of fluids. Modelling these as noise in the velocity field leads to a random deviation from each trajectory. This deviation is examined within the context of small (multiplicative) stochasticity applying to a two-dimensional unsteady flow operating over a finite-time. It is proven that the deviation's expectation is zero, and that its variance is bounded by a quantity defined to be the stochastic sensitivity. The stochastic sensitivity field provides a measure of uncertainty for trajectories beginning at each location. An easily computable expression for the stochastic sensitivity is derived. Monte Carlo simulations are used on a model flow to quantitatively validate the usage of the stochastic sensitivity, and moreover demonstrate the significant potential of stochastic sensitivity as a new tool for identifying coherent structures in flows even when the velocity is only available as data.

Shaun Bullett (Queen Mary University of London)TBAAbstract: Tuesday, 30 January 2018 14:00 Huxley 139
Ben Mestel (The Open University)Quasiperiodic renormalisation for general rotation numberAbstract: Starting from familiar number expansions (decimal, binary etc), we develop the dynamic expansions that form the basis of general quasiperiodic renormalisation, a review of which forms the second part of the talk.
