本文的主要结果是解决了比例尺寸截面的同构Busemann-Petty问题,如下所示。设0<λ<1,k>λn,K,L是Rn中的原点对称凸体,满足不等式|K∩H|≤|L∩H|,∀H∈Gr n−k,其中Gr n−k是Rn的(n−k)维子空间的Grassman空间,|K|表示真维体.则|K|n−k n≤Ck((1−⁡λ)3λ)k|L|n−k n,其中C是绝对常数。
The main result of this note is a solution to the isomorphic Busemann–Petty problem for sections of proportional dimensions, as follows. Suppose that 0< λ< 1, k> λ n, and K, L are origin-symmetric convex bodies in R n satisfying the inequalities| K∩ H|≤| L∩ H|,∀ H∈ Gr n− k, where Gr n− k is the Grassmanian of (n− k)-dimensional subspaces of R n, and| K| stands for volume of proper dimension. Then| K| n− k n≤ C k ((1− log⁡ λ) 3 λ) k| L| n− k n, where C is an absolute constant.
