Talk:Mixed volume

Notation
At a certain point in the article the bodies Ki seem to disappear and some mysterious quantities Ti appear instead. Are these supposed to be the same? Deltahedron (talk) 18:18, 17 April 2013 (UTC)

1/n! missing in the definition.
I think we want the definition to be coherent with the property V(T,...,T)=V(T) we need to divide the actual definition by n!. That is: $$ V(T_1, \ldots, T_n) =\frac{1}{n!} \left. \frac{\partial^n}{\partial \lambda_1 \cdots \partial \lambda_n}\right|_{\lambda_1 = \cdots = \lambda_n = +0} \mathrm{Vol}_n(\lambda_1 T_1 + \cdots + \lambda_n T_n).$$ — Preceding unsigned comment added by Bongilles (talk • contribs) 15:53, 4 September 2013 (UTC)
