Sur l'absence de mélange pour des flots spéciaux au-dessus d'une rotation irrationnelle

M. Lemańczyk (2000)

Colloquium Mathematicae

Similarity:

We prove the absence of mixing for special flows built over (1) an irrational rotation and under a function whose Fourier coefficients are of order O(1/|n|), and (2) an irrational rotation (satisfying a diophantine condition) and under a function having a finite number of singularities of a logarithmic type. These results generalize two theorems of Kochergin.
