Dynamical Entropy for the Quantized CAT Map
(34K, LaTeX)

ABSTRACT.  We estimate the dynamical entropy for the quantized CAT map. It turns
out that the result depends on the rotation parameter and positivity
of the dynamical entropy demands asymptotic abelianness. Further the
estimates offer a counterexample to the additivity of the dynamical
entropy for tensor products.
