Summary: We call a sequence \((T_n)\) of measure preserving transformations strongly mixing if \(P(T_n^{-1}A\cap B)\) tends to \(P(A)P(B)\) for arbitrary measurable \(A\), \(B\). We investigate whether one can pass to a suitable subsequence \((T_{n_k})\) such that \(\frac 1K \sum_{k=1}^K f(T_{n_k}) \rightarrow \int f dP\) almost surely for all (or “many”) integrable \(f\).
