| Oct 12, 2012 at 7:56 | comment | added | S. Carnahan♦ | Yes, I would also like to know if $\phi$ is an isomorphism of rings, abelian groups, sets, $F[x]$-modules, or something else. Right now, the question is rather underspecified. | |
| Oct 12, 2012 at 7:37 | comment | added | Noah Stein | @S. Carnahan: If so, $\psi$ would always exist even for $\phi$ without an inverse because $F[x]$ is free. | |
| Oct 12, 2012 at 6:47 | comment | added | S. Carnahan♦ | Do you demand that $\phi$ be $F$-linear? | |
