Using small perturbations to control chaos
The extreme sensitivity of chaotic systems to tiny perturbations (the ‘butterfly effect’) can be
used both to stabilize regular dynamic behaviours and to direct chaotic trajectories rapidly to …

Seasonality and the requirements for perpetuation and eradication of viruses in populations.
JA Yorke, N Nathanson, G Pianigiani… - American Journal of …, 1979 - europepmc.org
Perpetuation of a virus in a population is distinct from the ability to persist in a cell culture or
individual host. Parameters which determine perpetuation include: 1) the size of the …

Period three implies chaos
TY Li, JA Yorke - The theory of chaotic attractors, 2004 - Springer

Controlling chaos
It is shown that one can convert a chaotic attractor to any one of a large number of possible
attracting time-periodic motions by making only small time-dependent perturbations of an …

The dimension of chaotic attractors
Dimension is perhaps the most basic property of an attractor. In this paper we discuss a
variety of different definitions of dimension, compute their values for a typical example, and …

On the existence of invariant measures for piecewise monotonic transformations
A Lasota, JA Yorke - The Theory of Chaotic Attractors, 2004 - Springer
A class of piecewise continuous, piecewise C transformations on the interval [0, 1] is shown
to have absolutely continuous invariant measures.
