On the approximation of a polytope by its dual $L_{p}$-centroid bodies
  We show that the rate of convergence on the approximation of volumes of a convex symmetric polytope P in R^n by its dual L_{p$-centroid bodies is independent of the geometry of P. In particular we show that if P has volume 1, lim_{p\rightarrow \infty} \frac{p}{\log{p}} (\frac{|Z_{p}^{\circ}(P)|}{|P^{\circ}|} -1) = n^{2}.   We provide an application to the approximation of polytopes by uniformly convex sets.
