- Abstract:
- By the Dambis-Dubins-Schwarz theorem, any stochastic integral M of Brownian motion can be written as a time-changed Brownian motion. Rosinski and Woyczynski (1986) and Kallenberg (1992) showed that in this statement Brownian motion can be replaced with (symmetric) α -stable Lévy motion. Using the cumulant process of a semimartingale, we give new short proofs. Moreover, we show that the statement cannot be extended to any other Lévy processes.
