Talk:Approximation property

[Untitled][edit]

This page contains references to space " $l_{p}$ ". Is that supposed to be $l^{p}$ ? -- JanCK (talk) 22:51, 6 August 2008 (UTC)[reply]

- That's just a different notation. Some authors put p below, reserving the upper index for dimension. 147.231.88.128 (talk) 15:06, 3 September 2010 (UTC)[reply]

Counterexamples[edit]

Can a reference be added to the last sentence of the third paragraph? "The spaces \ell^{p} for p\neq 2 and c_0 have closed subspaces that do not have the approximation property." Boy Waffle (talk) 15:46, 21 June 2018 (UTC)[reply]
