DESCRIPTION:One of the hallmarks of chaos is that nearby initi
al conditions separate at exponential rate. This e
xponential complexity might be reasonably assumed
to produce exponential rates of mixing in fluid de
vices which aim to exploit chaotic dynamics to sti
r efficiently. However\, experiments suggest that
in practice\, boundaries slow mixing rates down. W
e give rigorous results from smooth ergodic theory
of hyperbolic dynamical systems which establish p
olynomial mixing rates for a class of simple model
of bounded flows.\n
