Webtheorem was originally derived from the Palm-Khintchine formulas; a direct proof was given in Cramer-Leadbetter [1]. Its real simplicity seems to be obscured by the slightly complicated presentation of the proof. The same may be said of the proof of Dobrushin's theorem involving an unnecessary contraposition as well as some epsi-lonics.

Theorem 2.1 provides a counterexample in the general (nonergodic) case. For arithmetic progressions of length < 5, the result analogous to Theo-rem 1.2 does not hold. Using theresult of Ruzsa contained in Appendix, in Section 2.3 we show Theorem 1.3.
