| Nov 23, 2010 at 3:27 | comment | added | AnonymousCoward | Im sorry, maybe its a poor question. If you can think of a way to improve it, then be my guest. Im not quite sure how I would do that, maybe the question is too general. | |
| Nov 23, 2010 at 3:03 | comment | added | Jonas Meyer | @GottfriedLeibniz: But what sort of general necessary conditions are you looking for to make functions commute? Different sets of commuting functions will commute for different reasons. Are you looking for a bunch of examples? | |
| Nov 23, 2010 at 2:57 | comment | added | AnonymousCoward | @jonas yes this question was mainly motivated from an analysis perspective originally, so those properties would be nice to consider. It would narrow the search a little bit. But im really open to anything since its more of a general inquiry. | |
| Nov 23, 2010 at 2:49 | comment | added | Jonas Meyer | I don't understand the question. What sort of conditions are you looking for? What sort of functions? Do you want to assume continuity, differentiability, linearity, etc.? | |

| Nov 23, 2010 at 2:31 | comment | added | AnonymousCoward | Yes, but thats just multiplication by a constant in $\mathbb{C}$ so its not very interesting I think. Like I noted, in higher dimensions we have the maximal tori of the orthogonal group I think. | |
