Lutwak提出了凸体的Lp-曲率映象的概念,并证明了凸体与其Lp-曲率映象的体积之间的一个不等式.本文给出了Lutwak结果的一个一般形式,继而证明了凸体与其Lp-曲率映象的极的体积之间的一个不等式,并得到了凸体的Lp-投影体和Lp-曲率映象的体积之间的一个不等式.
Lutwak showed the notion of Lp - curvature image and proved an inequality for the volumes of convex body and its Lp - curvature image. This paper gives a genaral form than Lutwak's result. Further, the authors establish an inequality for the volumes contained convex body and the polar of its Lp -curvature image, and obtain an inequality for the volumes of Lp-projection body and Lp-curvature image.
