A. Bouzouina et S. Debievre, EQUIPARTITION OF THE EIGENFUNCTIONS OF QUANTIZED ERGODIC MAPS ON THE TORUS, Communications in Mathematical Physics, 178(1), 1996, pp. 83-105
We give a simple proof of the equipartition of the eigenfunctions of a
class of quantized ergodic area-preserving maps on the torus. Example
s are the irrational translations, the skew translations, the hyperbol
ic automorphisms and some of their perturbations.
