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.
