| Oct 7, 2015 at 7:08 | comment | added | Bill Johnson | True, Rauni, but the proof of the factorization theorem gives an injective $J$. Also, if you have such a factorization with a non injective $J$, you can mod out the kernel of $J$ to get a factorization through another reflexive space for which the mapping from the reflexive space is injective. | |
| Oct 6, 2015 at 5:08 | comment | added | Rauni | Thank You for Your alternate proof. I used it in a seminar. But it seems to me that we do not use injectivity of J anywhere? | |

| Oct 1, 2015 at 21:46 | comment | added | Rauni | When You say "By the factorization theorem for weakly compact operators", do You refer to the DFJP Factorization or to some other result? | |
