# Renormalisation of the two-dimensional border-collision normal form

@inproceedings{Ghosh2021RenormalisationOT, title={Renormalisation of the two-dimensional border-collision normal form}, author={Indrani Ghosh and David J. W. Simpson}, year={2021} }

We study the two-dimensional border-collision normal form (a four-parameter family of continuous, piecewise-linear maps on R2) in the robust chaos parameter region of [S. Banerjee, J.A. Yorke, C. Grebogi, Robust Chaos, Phys. Rev. Lett. 80(14):3049– 3052, 1998]. We use renormalisation to partition this region by the number of connected components of a chaotic Milnor attractor. This reveals previously undescribed bifurcation structure in a succinct way.

The collection of all non-degenerate, continuous, two-piece, piecewise-linear maps on R2 can be reduced to a four-parameter family known as the two-dimensional border-collision normal form. We prove…

Several important features of the scenario are shown to be universal, and three examples are given, and infinite coexistence is proved directly by explicitly computing periodic solutions in the infinite sequence.

The multipliers of a fixed point of a piecewise-smooth, continuous map may change discontinuously as the fixed point crosses a discontinuity under smooth variation of parameters, similar to the Neimark–Sacker bifurcation of a smooth map.
