Haberl and Ludwig defined the notions of L_p intersection bodies. In this paper,we introduce the L_p mixed intersection bodies, and establish some geometric inequalities for L_p mixed intersection bodies. Furthermore, the Busemann-Petty type problem for L_p mixed intersection bodies are shown. 相似文献

In this paper, by using the theory and method of distance geometry, we study the geometric inequality of a n-dimensional simplex in the spherical space and establish two geometric inequalities involving the edge-length and volume of one simplex and the volume,height and(n-1)-dimensional volume of the side of another simplex in the n-dimensional spherical space. They are the extensions of the results [10] in the n-dimensional Euclidean geometry to the n-dimensional spherical space. 相似文献

1988年,Lutwak首次明确地提出了经典相交体的概念.2005年,Haberl和Ludwig对经典相交体进行了推广,给出了L_p-相交体的概念.最近,汪卫等提出了广义相交体的概念.主要利用L_p-Brunn-Minkowski理论、Hlder积分不等式和Minkowski积分不等式,研究了广义相交体的单调性,并建立了关于径向线性组合和L_p-调和Blaschke组合的Brunn-Minkowski型不等式. 相似文献

Some new inequalities of Hermite-Hadamard's integration are established. As for as inequalities about the righthand side of the classical Hermite-Hadamard's integral inequality refined by S Qaisar in [3], a new upper bound is given. Under special conditions,the bound is smaller than that in [3]. 相似文献

本文利用由两个Hilbert-Schmidt Bessel序列生成的有界线性算子和参数λ∈■构建了Hilbert-Schmidt框架的一些新的不等式.事实表明,当选取恰当的Hilbert-Schmidt Bessel序列和参数λ时,已有的一些关于这个主题的结果可由本文结果推导得到.此外,本文还给出了Hilbert-Schmidt框架的与已有框架不等式相比具有新的结构的三角不等式. 相似文献

It is proved that if λ_1, λ_2, ···, λ_7are nonzero real numbers, not all of the same sign and not all in rational ratios, then for any given real numbers η and σ, 0 σ 1/16, the inequality |λ_1x~2_1+ λ_2x~2_2+∑7 i=3λ_ix~4_i+ η| ( max1≤i≤7|x_i|)~(-σ)has infinitely many solutions in positive integers x_1, x_2, ···, x_7. Similar result is proved for |λ_1x~2_1+ λ_2x~2_2+ λ_3x~2_3+ λ_4x~4_4+ λ_5x~4_5+ λ_6x~4_6+ η| ( max1≤i≤6|xi|)-σ.These results constitute an improvement upon those of Shi and Li. 相似文献
