Does H_infy have the AP? Nobody knows for 60 years... For genious young one (hope to find in Earth).

I think the point is that if the Hardy space $H^\infty(T)$ did have the (Grothendieck) approximation property -- and this is utterly standard terminology in the field of Banach spaces, for those snarking at the abbreviations -- then MO would not be the first place this is announced! – Yemon Choi Jul 12 2010 at 17:57
