Abstract

Let Bx ⊆ Rn denote the Euclidean ball with diameter [0, x], i.e., with with center at x/2 and radius x/2. We call such a ball a petal. A flower F is any union of petals, i.e., (formula presented) for any set A ⊆ Rn. We showed earlier in [9] that the family of all flowers F is in 1-1 correspondence with K0 – the family of all convex bodies containing 0. Actually, there are two essentially different such correspondences. We demonstrate a number of different nonlinear constructions on F and K0. Towards this goal we further develop the theory of flowers.
