Abstract

It is shown that the cubic nonconventional ergodic average of order 2 with M\"obius and Liouville weight converge almost surely to zero. As a consequence, we obtain that the Ces\`aro mean of the self-correlations and some moving average of the self-correlations of M\"obius and Liouville functions converge to zero.

Comments

In this version, we put in the surface our main result on the Cesaro mean of the auto-correlation of M\"obius and Liouville which is related to the very recent results of K. Matom\"aki and M. Radziwi{\l}{\l}, and K. Matom\"aki, M. Radziwi{\l}{\l} and T. Tao
