Thus, the sequence hf n;e 1ilies in [ 1;1] and there is a subsequence of the f n for which it converges, call it f n;1. We can inductively form f n;m by extracting a subsequence of f n;m 1 which converges along e m. Taking the diagonal sequence (f n;n) n2N, we have a subsequence of f n which is weakly convergent.
