Hadwiger showed by computing the intrinsic volumes of a regular sim-plex that a rectangular simplex is a counterexample to Wills's conjecture for the relation between the lattice point enumerator and the intrinsic volumes in dimensions not less than 441. Here we give formulae for the volumes of spherical polytopes related to the intrinsic volumes of the(More)
The second theorem of Minkowski establishes a relation between the successive minima and the volume of a 0-symmetric convex body. Here we show corresponding inequalities for arbitrary convex bodies, where the successive minima are replaced by certain successive diameters and successive widths. We further give some applications of these results to successive(More)
We study the following generalization of the inradius: For a convex body K in the d-dimensional Euclidean space and a linear k-plane L we define the inradius of K with respect to L by rL(K) = max{r(K; x + L) : x ∈ E d }, where r(K; x + L) denotes the ordinary inradius of K ∩ (x + L) with respect to the affine plane x + L. We show how to determine rL(P) for(More)
