Minkowski valuations

Abstract: Abstract. Centroid and difference bodies define SL(n) equivariant operators on convex bodies and these operators are valuations with respect to Minkowski addition. We derive a classification of SL(n) equivariant Minkowski valuations and give a characterization of these operators. We also derive a classification of SL(n) contravariant Minkowski valuations and of L p -Minkowski valuations.

“…Perhaps the best known result is Hadwiger's classification of continuous rigid motion invariant valuations on K n (see [16,21] and [1,2,3,4,5,6,12,18,19,20,28,37,38] for further results on real-valued valuations). More recently, Minkowski valuations, that is, valuations Z : W → K n , where addition in K n is Minkowski addition, have attracted a lot of interest (see [15,17,23,24,25,26,43,45,46]). Ludwig [25] proved that two important operators on convex bodies can be characterized as Minkowski valuations with certain invariance properties with respect to the special linear group: projection bodies and moment bodies.…”

Whereas projection bodies appear in the classification of valuations on Sobolev spaces [27], this is not the case for moment bodies.…”
