Abstract

Let QQ be the unit cube in Rn\mathbb{R}^n and HH a hyperplane thru the Origin. The intersection HQH\cap Qis called (central) Cube slice and was investigated by Henesley, Vaaler, Ball and others. A zonoid is the range of a measure into RnR^n. Our interest is : When is a cube slice a zonoid? We only give an example of a cube slice in R4\mathbb{R}^4 that is not a zonoid. We also give examples ofslices that are zonoids. For ex let H: ax+y+z+t=0ax + y +z + t =0h If a3 a\ge 3 then the slice is a zonoid( zonotope) Otherwise it isnot ,
