Logarithmic moving averages

Journal of Mathematical Analysis and Applications, 2015
We introduce a moving average summability method, which is proved to be equivalent with the logarithmic $\ell$-method. Several equivalence and Tauberian theorems are given. A strong law of large numbers is also proved.
