Streszczenie
We study a nonconventional ergodic average for asymptotically abelian weakly mixing $C^*$-dynamical systems, related to a second iteration of Khinchin's recurrence theorem obtained by Bergelson in the measure-theoretic case. A noncommutative recurrence theorem for such systems is obtained as a corollary.
