In this paper, it is proved that the radial pth mean body RpK(p 〉 0) is homothetic to the difference body DK when K is a simplex, Furthermore, the equality Rp(Rq) = Rq(Rp) is established when p 〉 0 and q 〉 0. It is also proved the Brunn-Minkowski inequality of radial pth mean body of simplex and uniqueness property. 相似文献

Let K be a 1-unconditional convex bodies in Euclidean spaces.We study the asymptotic properties of two affine invariants m2(K) and S2(K) for a random simplex inside K.As an application,we discuss the asymptotic properties of two affine invariants m2(Bpn ) and S2(Bpn ),where Bpn = {x ∈ Rn : ‖x‖ p 1}. 相似文献

在定义了R^2的单调范数以后,得到了RS集对两个最佳元逼近的新特征。当X是p一致凸Banach空间,证明了凸集对两个元的最佳同时逼近必是 p阶强唯一的(p>1)。 相似文献

利用泰勒公式法证明一个凸函数命题,由该命题的结论可简单地导出几个熟知的重要不等式,如詹生(Jensen)不等式、算术-几何-调和平均不等式、杨氏(Young)不等式、霍尔德(Holder)不等式、柯西-希瓦兹(Cauchy—Schwartz)不等式等。 相似文献
