May 5, 2011 at 22:14 | comment | added | Tony Huynh | I am using the notation $2- \chi$ for it, but am just wondering if it has a widely accepted name. | |
May 5, 2011 at 22:07 | comment | added | Simon Rose | @Mark - Yeah, that's sort of what I was getting at. | |
May 5, 2011 at 21:48 | comment | added | Mark Grant | Indeed. So why not just call it $2-\chi$? | |
May 5, 2011 at 21:02 | comment | added | Tony Huynh | Indeed. This is another reason why this is the more natural definition, among others. | |
