| Beschreibung: | We explicitly calculate the Hausdorff dimension of the graph and range of an isotropic stable Lévy process X plus deterministic drift function f. For that purpose we use a restricted version of the genuine Hausdorff dimension, which is called the parabolic Hausdorff dimension. It turns out that covers by parabolic cylinders are optimal for treating self-similar processes, since their distinct non-linear scaling between time and space geometrically matches the self-similarity of the processes. We provide explicit formulas for the Hausdorff dimension of the graph and the range of X+f. In sum, the parabolic Hausdorff dimension of the drift term f alone contributes to the Hausdorff dimension of X+f. Furthermore, we derive some formulas and bounds for the parabolic Hausdorff dimension. | |||||||
