Subsequence?

[edit]

The proof uses the fact that each sequence in a compact space has a converging subsequence. This is not true in general (non-metrizable) locally convex spaces. Do we have to take a subnet instead of a subsequence? --130.83.2.27 (talk) 12:27, 30 January 2013 (UTC)[reply]

Yes, it should be a subnet, not a subsequence. This proof is taken from Reed-Simon volume 1 page 152, and they use subnets. I've just corrected this. — Preceding unsigned comment added by 197.34.111.12 (talk) 08:22, 27 March 2015 (UTC)[reply]
