X射线变换的两个界
Two bounds for the x-ray transform
摘要:
我们使用Katz和Tao的算术组合方法给出了当d \geq 4时R^d上x射线变换的混合范数估计。作为应用,我们得到了(d,k)集的豪斯多夫维数的一个改进的估计,(d,k)集是R^d的包含每个k-平面平移的子集.
英文摘要:
We use the arithmetic-combinatorial method of Katz and Tao to give mixed-norm estimates for the x-ray transform on R^d when d \geq 4. As an application, we obtain an improved estimate for the Hausdorff dimension of (d,k) sets, which are subsets of R^d containing a translate of every k-plane.
