## Abstract

A certain class of stochastic summability methods of mantissa type is introduced and its connection to almost sure limit theorems is discussed. The summability methods serve as suitable weights in almost sure limit theory, covering all relevant known examples for, e.g., normalized sums or maxima of i.i.d. random variables. In the context of semistable domains of attraction the methods lead to previously unknown versions of semistable almost sure limit theorems.

Let (*X*
_{k}) be a sequence of independent r.v.’s such that for some measurable functions *gk* : **R**
^{k} → **R** a weak limit theorem of the form

*G*. By a general result of Berkes and Csáki (“universal ASCLT”), under mild technical conditions the strong analogue

*d*

_{k}) is a logarithmic weight sequence and

*D*

_{N}= ∑

_{k=1}

^{N}

*d*

_{k}. In this paper we extend the last result for a very large class of weight sequences (

*d*

_{k}), leading to considerably sharper results. We show that logarithmic weights, used traditionally in a.s. central limit theory, are far from optimal and the theory remains valid with averaging procedures much closer to, in some cases even identical with, ordinary averages.
