Greetings! I am currently completing an undergrad prac on the lorenz attractor, and I'm having some trouble with the aperiodicity of the attractor. Having spent some time looking at lots of pretty pictures, I can accept with no worries the idea that the whole structure forms an infinite layering effect, and therefore the attractor can easily be aperiodic. The problem is how to say this in a report. Is there any proof that the attractor is aperiodic?? Some texts refer to the extreme unlikelihood(?) of this, but this only implies that periodicity does occur. If it does, can it be pinned down? Is there then any test for periodicity vs. aperiodicity, eg. values for sigma, b and r, or do the initial conditions ruin all hope?? Other texts seem to take it for granted that it is aperiodic. Is the problem the fact that it is simulated in a computer, which theoretically is not cabable of resolving ifinitesimal differences? Before anyone tells me to read Sparrow, it's been stolen/hidden in our library. All help/info/ideas gladly accepted!! Cheers, Marty.
