Convex polytopes are the convex hulls of a finite set of points in Euclidean spaces. They have rich combinatorial, arithmetic, and metrical theory, and are related to toric varieties and to linear programming

Monge-Ampère measures and Kazarnovskii pseudovolume

Let $\Gamma\subset\mathbb C^n$ be a convex polytope and let $h_\Gamma(z)=\max_{v\in\Gamma}{\rm Re}\langle z,v\rangle$ be its support function with respect to the standard scalar product on $\mathbb C^ …

Monge-Ampère measures and Kazarnovskii pseudovolume

I finally found a purely current theoretical proof of the equality \begin{equation*} \mu_1(B_{2n}) = 2^{n-1}(n-1)! \sum_{\Delta\in{\mathcal B}(\Gamma,1)} {\mathop{\rm vol\,}\nolimits}_{1}(\Delta) {\ma …

On intrinsic volumes

Let $\Gamma$ be a convex polytope in $\mathbb R^n$. The $k$-th intrinsic volume of $\Gamma$ is the number $$ \text{v}_k(\Gamma)=\sum_{\Delta\in{\mathcal B}(\Gamma,k)}\text{vol}_k(\Delta)\psi_\Gamma(\D …

construction of four dimensional regular convex polytopes

Could anybody give me a reference book about the explicit construction of the 6 regular four dimensional convex polytopes. I cannot easily find Schläfli's original paper so I am looking for a modern r …
