| Nov 9, 2012 at 1:12 | comment | added | Patricia Hersh | @Andreas: That's a good idea! I will add that some time soon. | |
| Nov 9, 2012 at 0:43 | comment | added | Andreas Blass | People who haven't seen $h$-vectors before might find the definition somewhat unnatural. Since you're interested in the polynomials, not just the vectors, it might be worth mentioning the nice relationship between the $h$- and $f$-polynomials, shifting the argument by 1. | |
