Abstract

We introduce floating bodies for convex, not necessarily bounded subsets of Rn\mathbb{R}^n. This allows us to define floating functions for convex and log concave functions and log concave measures. We establish the asymptotic behavior of the integral difference of a log concave function and its floating function. This gives rise to a new affine invariant which bears striking similarities to the Euclidean affine surface area.
