| Oct 24, 2015 at 22:56 | comment | added | Igor Rivin | @VesselinDimitrov Thanks! I will look, but is there some conceptual reason why something like this should be true (other than it would be shocking otherwise)? | |
| Oct 24, 2015 at 22:35 | comment | added | Vesselin Dimitrov | Yes, this is true: the discriminant is geometrically irreducible. This is proved, in higher generality, on page 15 (Ch. 1.1. B) of Gelfand, Kapranov and Zelevinsky's book, Discriminants, Resultants and Multidimensional Determinants. | |
