Abstract

We introduce f-divergence, a concept from information theory and statistics, for convex bodies in ℝⁿ. We prove that f-divergences are SL(n) invariant valuations and we establish an affine isoperimetric inequality for these quantities. We show that generalized affine surface area and in particular the L_paffine surface area from the L_pBrunn Minkowski theory are special cases of f-divergences.
