Entropy via multiplicity
Boris Kruglikov, Martin Rypdal
The topological entropy of piecewise affine maps is studied. It is shown that singularities may contribute to the entropy only if there is angular expansion and we bound the entrop…

A piece-wise affine contracting map with positive entropy
Boris Kruglikov, Martin Rypdal
We construct the simplest chaotic system with a two-point attractor.
