摘要:

首先引入星体弦长积分的概念,研究了其性质并建立了有关星体弦长积分的不等式.作为应用,给出相交体的星对偶的Brunn-Minkowski型不等式.

关键词: 对偶均质积分, 弦长积分, 相交体, 星对偶, 星体

Abstract:

The i th chord-integrals of star bodies are introduced, and some inequalities and propositions for the chord-integrals of star bodies established. Asan application, the Brunn-Minkowski inequality for star duality of intersection bodies is obtained.

Key words: chord-integrals, dual quermass integrals, mixed intersection bodies, star duality
