  • 摘要:Xt)=(X1t),…,XNt))为一d-维过程,其中Xit)为αi-阶di-维稳定过程.设0<αn<…<α1≤2,d=d1+…+dN.本文中,我们获得了,当α1d1时稳定分量过程Xt)关于Borel集E的象XE)的Hausdorff测度和Packing测度的一致上界和一致下界,当α1>d1时得到了相应测度的一个一致上界.同时我们给出了一致维数结果。

     

    Abstract: LetXt)=(X1t),…,XNt)) be a d-dimensional process, where Xit) is a αi,-order stable di-dimensional process. Assume 0<αn<…<α1≤2,d=d1+…+dN. In this paper, when α1d1, we obtain the uniform bounds on the Hausdorff and packing measure of the image XE) of a Borel set E under a process Xt) with stable components. When α1d1, the uniform upper is obtained. Uniform dimension theorem is given.
