| Oct 18, 2013 at 15:03 | comment | added | Aurel | @suv...rit: since in this case the matrices are already Hermitian, they are automatically semisimple so you can simply say "regular". | |
| Oct 18, 2013 at 14:23 | comment | added | Suvrit | @PeterMueller: I like this suggestion, also because it is a single word as opposed to two words like "regular semisimple" or "multiplicity free" or "beatup (sic.) matrices" :-) | |

| Oct 18, 2013 at 11:40 | comment | added | Amritanshu Prasad | To me a simple matrix is one whose characteristic polynomial is irreducible. | |
| Oct 18, 2013 at 11:25 | comment | added | Peter Mueller | Another suggestion is separable, because the characteristic polynomial is separable. | |

| Oct 18, 2013 at 8:02 | comment | added | Mark Meckes | @NickGill: Anything? Let's try out randomlists.com/random-adjectives to test that. "Paltry matrices" or "upbeat matrices", perhaps? | |
| Oct 18, 2013 at 7:31 | comment | added | Nick Gill | I don't know of any established terminology but surely `simple' is a candidate for the most over-used adjective in mathematics. Anything else would be better!! | |
