| Apr 19, 2010 at 21:13 | comment | added | Vladimir Dotsenko | Keith, thanks! Why don't you post it as an answer here? I think it's a bit misleading that the accepted answer to this question states that every nxn traceless matrix over a PID is a commutator! | |
| Apr 19, 2010 at 14:04 | comment | added | KConrad | Vladimir, I wrote to Zak Mesyan (who wrote a paper on trace 0 and commutators) and he told me that whether an arbitrary nxn matrix over a PID with trace 0 is a commutator is still open as far as he knows. | |

| Apr 18, 2010 at 20:29 | comment | added | KConrad | I have written to someone who has worked on these kinds of problems and will post a reply when I get it. | |
| Apr 18, 2010 at 20:22 | comment | added | KConrad | Vladimir, that is my .pdf file you linked to and I actually do not have a good citation! I may have just read the MathSciNet review as Jack did without looking at the Rosset--Rosset article itself. So I have now removed that claim from the .pdf file and will see if I can find someone to settle this question. ой.... | |
