|Title:||Generalization of the Blumenthal-Getoor Index to the Class of Homogeneous Di usions with Jumps and some Applications|
|Abstract:||We introduce the probabilistic symbol for the class of homogeneous diffusions with jumps (in the sense of Jacod/Shiryaev). This concept generalizes the well known characteristic exponent of a Lévy process. Using the symbol we introduce eight indices which generalize the Blumenthal- Getoor index beta and the Pruitt index delta These indices are used afterwards to obtain growth and Hölder conditions of the process. In the future the technical main results will be used to derive further fine properties. Since virtually all examples of homogeneous diffusions in the literature are Markovian, we construct a process which does not have this property.|
