| Nov 2, 2023 at 6:30 | comment | added | David Loeffler | I heard you the first time – you don't need to "@" tag someone who is already part of the comment exchange, they'll already get the notification. (It's sometimes done anyway when there are lots of different people involved in the conversation but that's not the case here.) | |
| Nov 2, 2023 at 6:29 | comment | added | Richard | @DavidLoeffler Yes $m=1$ is trivial. When $m>1$ $\phi$ is not linear and that is the hard part. | |
| Nov 1, 2023 at 15:08 | comment | added | David Loeffler | Have you tried working out the $m = 1$ case first? In this case you're just looking for everything that commutes with a given linear endomorphism; and there are three cases according to whether $\phi$ is (a) diagonalisable with distinct eigenvalues, (b) scalar, or (c) a single 2x2 Jordan block, all of which you can easily bash out by hand. | |
