Affine invarianz

WebAn affine invariant point on the class of convex bodies K n in R n, endowed with the Hausdorff metric, is a continuous map from K n to R n that is invariant under one-to-one affine transformations A on Rn, that is, p (A (K)) = A (p (K)). We define here the new notion of dual affine point q of an affine invariant point p by the formula q (K p (K ...
