$L_p$ Minkowski Valuations on polytopes

Abstract

For $1\le p<\infty$, Ludwig, Haberl and Parapatits classified $L_p$ Minkowski valuations intertwining the special linear group with additional conditions such as homogeneity and continuity. In this paper,a complete classification of $L_p$ Minkowski valuations intertwining the special linear group on polytopes without any additional conditions is established for $p\ge 1$ including $p=\infty$. For $n=3$ and $p=1$, there exist valuations not mentioned before.
