| Abstract: |
| In this paper, we study the problem of the Orlicz projection bodies recently introduced by Lutwak, Yang and Zhang. By using the linear invariant property of Orlicz projection bodies, we obtain the result that the Orlicz projection bodies of ellipsoids are still ellipsoids. As examples, we compute two concrete support functions of Orlicz projection bodies of the unit ball for two specific convex functions. |
