摘要

我们研究曼德布罗特乘性级联measure mu\\mudd维单位立方体上的傅里叶维数 dimFmu\\dim_F\\mu。我们证明,如果 mu\\mu是由一个亚指数随机变量生成的级联measure,则\n\ndimFmu=min2,dim2mu\\dim_F\\mu=\\min\\{2,\\dim_2\\mu\\}\,,\n\n其中 dim2mu\\dim_2\\mumu\\mu的相关维数,且具有显式公式。对于在圆盘 SsubsetmathbbR2S\\subset\\mathbb{R}^2上的级联,我们得到\n\ndimFmu>=fracdim2mu2+dim2mu\\dim_F\\mu>=\\frac{\\dim_2\\mu}{2+\\dim_2\\mu}\,。\n\n
