But in case $A$ is a linear subspace itself (which was my primary interest), the answer is trivial as Wolfgang pointed out. Thanks for your time. | |

| Aug 14, 2012 at 8:39 | comment | added | Yemon Choi | Just to clarify: we can define linear subspaces $A_u$ and $A_a$ where the former consists of all unconditionally convergent sums of things in $A$, and the latter consists of all absolutely convergent sums of things in $A$, and you are asking under what "reasonable" conditions $A_u=A$ or $A_a=A$? | |
