Uncountably many cases of Filippov's sewed focus

Paul Glendinning, S. John Hogan, Martin Homer +2

The sewed focus is one of the singularities of planar piecewise smooth dynamical systems. Defined by Filippov in his book 'Differential Equations with Discontinuous Righthand Sides…

Heterodimensional cycles and noninvertible blenders in piecewise smooth two dimensional maps

Paul Glendinning

Heterodimensional cycles are heteroclinic cycles that connect periodic orbits whose unstable manifolds have different dimensions. This is a source of nonhyperbolic dynamics and uns…

Differentiable conjugacies for one-dimensional maps

P. A. Glendinning, D. J. W. Simpson

Differentiable conjugacies link dynamical systems that share properties such as the stability multipliers of corresponding orbits. It provides a stronger classification than topolo…

Unstable dimension variability, heterodimensional cycles, and blenders in the border-collision normal form

P. A. Glendinning, D. J. W. Simpson

Chaotic attractors commonly contain periodic solutions with unstable manifolds of different dimensions. This allows for a zoo of dynamical phenomena not possible for hyperbolic att…

Normal forms, differentiable conjugacies and elementary bifurcations of maps

Paul A. Glendinning, David J. W. Simpson

We strengthen the standard bifurcation theorems for saddle-node, transcritical, pitchfork, and period-doubling bifurcations of maps. Our new formulation involves adding one or two…

Inclusion of higher-order terms in the border-collision normal form: persistence of chaos and applications to power converters

David J. W. Simpson, Paul A. Glendinning

The dynamics near a border-collision bifurcation are approximated to leading order by a continuous, piecewise-linear map. The purpose of this paper is to consider the higher-order…
