Title: Noise-induced cascades in coupled dynamical systems

Abstract: In this talk I will discuss work with collaborators on coupled escape problems in nonlinear systems subject to noise. I will discuss qualitative changes in the weak noise behaviour associated with different types of cascading/domino effects and the use of quasipotential methods to estimate escape rates and escape sequences within such systems.
