摘要 该文获得了R^n中星体弦长积分的一些极限性质,建立了星体弦长积分的不等式,包括弦长积分和对偶均质积分之间的不等式以及对偶Blaschke-Santaló不等式. In this paper,we obtain some limit properties of chord-integrals in Rn,and establish some inequalities for chord-integrals of star bodies,including the inequalities between chord-integrals and dual quermass-integrals,the dual Blaschke-Santalo inequality and so on.
