comment Positive functionals on $\ell^\infty$
I had looked for questions about "positive operator", but I forgot to look for "non-negative operators"... anyway, I'm perfectly fine with using AC, and I fact I edited my question adding the Banach limits as another class of positive operators. Thank you for the links!

comment Is $\ell^1$ isomorphic to $L^1[0,1]$?
@Theo Buehler : your comment indeed seemed off-topic to me, but since it was a "nitpick", I didn't dare to question it... maybe you could edit the question title, setting it to something more meaningful and clear of "Basic Functional Analysis Question". Probably "Is $\ell^1$ isomorphic to $L^1$" would fit, or something similar...

comment A locally injective but non globally injective function?
$U$ was supposed to be open, but as your example shows, the interesting question arises when $U$ is connected.

@Didier Piau: you are right, I was thinking about continuos functions.
