Hare, On the height of the Sylvester resultant, Experimental Mathematics, 13:3 (2004) 331-341. | |

| Jul 22, 2013 at 18:53 | comment | added | minar | @DavidSpeyer: Thanks for your suggestion. Seeing your attempts, do you think it would be easier to count the nonzero terms of the determinant or maybe the $L_1$ norm of the vector of coefficients ? | |

| Jul 22, 2013 at 16:57 | comment | added | David E Speyer | I played around a little in Sloane's encyclopedia. For $\deg f=1$, the answer is $\deg g+1$. For $\deg f =2$, the answer appears to be oeis.org/A002623. No luck for the general question. Some sequences which look good at first but then fail are A227125, A202560 and A156353; the latter two were attempts at the variant problem of counting the nonzero terms in the determinant, before combining equal terms. | |
