Résumé

Two ergodic automorphisms of a Lebesgue space are called monotonely equivalent if they have metrically isomorphic induced automorphisms. We formulate properties of an automorphism of a Lebesgue space, similar to very weak Bernoulli and finitely determined. The difference is that instead of the Hamming metric on the space of words, we use a weaker metric $\rho^M$. These properties describe the class of quotient automorphisms of automorphisms monotonely equivalent to Bernoulli shifts. Bibliography: 12 titles.
