We prove uniform Hausdorff and packing dimension results for the inverse images of a large class of real-valued symmetric Levy processes. Our main result for the Hausdorff dimension extends that of Kaufman (1985) for Brownian motion and that of Song, Xiao, and Yang (2018) for $\alpha$-stable Levy processes with $1<\alpha<2$. Along the way, we also prove an upper bound for the uniform modulus of continuity of the local times of these processes.

对称 Lévy 过程的逆图像的统一尺寸结果

我们证明了一大类实值对称 Levy 过程的逆图像的统一 Hausdorff 和包装维度结果。我们对 Hausdorff 维度的主要结果扩展了 Kaufman (1985) 的布朗运动和 Song、Xiao 和 Yang (2018) 的关于 $\alpha$-stable Levy 过程的结果,$1<\alpha<2$。在此过程中,我们还证明了这些过程的本地时间的均匀连续性模数的上限。
