We introducef-divergence, a concept from information theory and statistics, for convex bodies in ℝn. We prove thatf-divergences areSL(n) invariant valuations and we establish an affine isoperimetric inequality for these quantities. We show that generalized affine surface area and in particular theLpaffine surface area from theLpBrunn Minkowski theory are special cases off-divergences.
