In this chapter, the following notions play the essential roles: zonotopes (finite sums of segments), zonoids (limits of zonotopes), projection bodies (zonotopes or zonoids whose support function values present the (n − 1)-dimensional orthogonal projection areas of given n-dimensional convex polytopes or convex bodies), polars of projection bodies, mixed projection bodies and projection maps, centroid bodies, and valuations (for the latter, see also Chapter 11 ).

摘要

In this chapter, the following notions play the essential roles: zonotopes (finite sums of segments), zonoids (limits of zonotopes), projection bodies (zonotopes or zonoids whose support function values present the (n − 1)-dimensional orthogonal projection areas of given n-dimensional convex polytopes or convex bodies), polars of projection bodies, mixed projection bodies and projection maps, centroid bodies, and valuations (for the latter, see also Chapter 11 ).
