Talk:Mixed volume

Notation

At a certain point in the article the bodies K_i seem to disappear and some mysterious quantities T_i 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)
