Influence of noise on scalings for inout intermittency
Ashwin, Peter; Covas, Eurico; Tavakol, Reza (American Physical Society, 2001)We study the effects of noise on a recently discovered form of intermittency, referred to as inout intermittency. This type of intermittency, which reduces to onoff in systems with a skew product structure, has been found ... 
In–out intermittency in partial differential equation and ordinary differential equation models
Covas, Eurico; Tavakol, Reza; Ashwin, Peter; Tworkowski, Andrew; Brooke, John M. (American Institute of Physics, 2001)We find concrete evidence for a recently discovered form of intermittency, referred to as in–out intermittency, in both partial differential equation (PDE) and ordinary differential equation (ODE) models of mean field ... 
Nonnormal parameter blowout bifurcation: an example in a truncated mean field dynamo model
Covas, Eurico; Ashwin, Peter; Tavakol, Reza (American Physical Society, 1997)We examine global dynamics and bifurcations occurring in a truncated model of a stellar mean field dynamo. This model has symmetryforced invariant subspaces for the dynamics and we find examples of transient type I ... 
Transverse instability for nonnormal parameters
Ashwin, Peter; Covas, Eurico; Tavakol, Reza (Institute of Physics, 1999)We consider the behaviour of attractors near invariant subspaces on varying a parameter that does not preserve the dynamics in the invariant subspace but is otherwise generic, in a smooth dynamical system. We refer to such ...
