摘要:
基于Zvavitch将Busemann-Petty问题推广到了一般测度，本文利用Radon变换研究了一般测度Busemann-Petty问题的稳定性。作为应用，我们建立了n(n≤4)维空间中的一个关于一般测度的超截面不等式。这些结果与Koldobsky利用Fourier变换证明的结论是一致的。
Zvavitch found a generalization of the Busemann-Petty problem to arbitrary measures. In this paper, we study the stability in the Busemann-Petty problem for arbitrary measures by using Radon transform. As application, we obtain a hyperplane inequality for arbitrary measures in dimensions up to four. These results are consistent with Koldobsky’s results which are obtained by using Fourier transform.
