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。
The ith chord-integrals of star bodies are introduced, and some inequalities and propositions for the chord-integrals of star bodies established. As an application, the Brunn-Minkowski inequality for star duality of intersection bodies is obtained.
