On Isomorphism Problem of Stationary Processes

A. H. Zaslavskiĭ

Novosibirsk

Abstract: The central problem in ergodic theory is that of isomorphism. In the paper the sufficient condition for isomorphism of the stationary process $\xi=(…,\xi_{-1},\xi_0,\xi_1,…)$, $\xi_n=0$, $1,…,l$, with some stationary process $\eta=(…,\eta_{-1},\eta_0,\eta_1,…)$, $\eta_n=\alpha_1,…,\alpha_m$, $m\leqq l$, is found. This condition is expressed in terms of a one-dimensional distribution of the process $\xi$. Isomorphism is constructed with the aid of elementary codes
$$(i)=\eta_1^i\eta_2^i\cdots\eta_{\omega_i}^i,\qquad i=1,…,l,$$
which code the elementary words
$$(i)=\underbrace{i00…0}_{\omega_i}.$$
One of the examples considered proves that it is possible to construct a system of elementary codes for any arbitrary $l$ and $m$. This system possesses some properties which secure unique decoding of the sequence $\eta$.
