    On Templeman averages and variation functions

  • Original language description

    Let S be a countable semigroup acting in a measure-preserving fashion (g ? T g ) on a measure space (?, A, ?). For a finite subset A of S, let |A| denote its cardinality. Let (A k ) k=1 ? be a sequence of subsets of S satisfying conditions related to those in the ergodic theorem for semi-group actions of A. A. Tempelman. For A-measureable functions f on the measure space (?, A, ?) we form for k ? 1 the Templeman averages ?k(f)(x)=|Ak|?1?g?AkTgf(x) and set V q f(x) = (? k?1|? k+1(f)(x) ? ? k (f)(x)|q)1/qwhen q ? (1, 2]. We show that there exists C > 0 such that for all f in L 1(?, A, ?) we have ?({x ? ?: V q f(x) > ?}) ? C(?? | f | d?/?). Finally, some concrete examples are constructed.
