众所周知, 对数Minkowski不等式和对数Aleksandrov-Fenchel不等式,最近已先后问世. 继这之后, 本文通过引进混合体积测度和 ?- 多元混合体积测度,并且利用新近建立的Orlicz-Aleksandrov-Fenchel不等式和经典的Hadamard积分不等式,建立了一个Orlicz空间上的 ?- 对数Aleksandrov-Fenchel不等式.这个Orlicz ?- 对数Aleksandrov-Fenchel不等式在特殊情况下, 分别产生了 Aleksandrov-Fenchel不等式,对数Minkowski不等式, Orlicz对数Minkowski不等式,对数 Aleksandrov-Fenchel不等式和Lp-对数Aleksandrov-Fenchel不等式. 相似文献

本文继文献[1]之后,进一步研究了自由基加成定位选择性(R值)对于反应介质的依赖性.以偏氟乙烯为受物,环丙基为进攻试剂,在80℃下,在十五种溶剂中测定了R值,从而肯定了R值对反应介质的依赖性.此种溶剂效应与各种溶剂参数皆无相关关系,而可能符合于溶剂分子的几何因素在起作用的设想.为验证有关机理的设想,文中还考察了二元混合溶剂体系中的R值,并从有关机理的假定出发,导出了R值与溶剂配比的关系式.计算结果与实验基本相符. 相似文献

In the paper, we establish a reversed Dresher’s integral inequality, based on the Minkowski inequality and an inequality due to Radon. Further, we prove Dresher-type inequalities for width-integrals of convex bodies and mixed projection bodies, respectively. 相似文献

In 1993 Lutwak established some analogs of the Brunn-Minkowsi inequality and the Aleksandrov-Fenchel inequality for mixed projection bodies. In this paper, following Lutwak, we give their polars forms. Further, as applications of our methods, we give a generalization of Pythagorean inequality for mixed volumes. 相似文献

In this paper, we first introduce a new concept ofdual quermassintegral sum function of two star bodies and establish Minkowski’s type inequality for dual quermassintegral sum of mixed intersection bodies,
which is a general form of the Minkowski inequality for mixed intersection bodies. Then, we give the Aleksandrov-Fenchel inequality
and the Brunn-Minkowski inequality for mixed intersection bodies and some related results. Our results present, for intersection
bodies, all dual inequalities for Lutwak’s mixed prosection bodies inequalities. 相似文献

The mixed width-integrals are defined and shown to have properties similar to those of the mixed volumes of Minkowski. An
inequality is established for the mixed width-integrals analogous to the Fenchel-Aleksandrov inequality for the mixed volumes.
An isoperimetric inequality (involving the mixed width-integrals) is presented which generalizes an inequality recently obtained
by Chakerian and Heil. Strengthened versions of this general inequality are obtained by introducing indexed mixed width-integrals.
This leads to an isoperimetric inequality similar to Busemann’s inequality involving concurrent cross-sections of convex bodies. 相似文献

In this paper, it is shown that a family of inequalities involving mixed intersection bodies holds. The Busemann intersection inequality is the first of this family. All of the members of this family are strengthened versions of classical inequalities between pairs of dual quermassintegrals of a star body. 相似文献
