Abstract (deu)
Following a paper of Marta Tyran-Kaminska we provide necessary and sufficient conditions for partial sum processes to converge to Lévy processes without Gaussian part in terms of random measures. In this context, we give an introduction to the theory of the space of right-continuous functions having left limits with Skorokhod’s J1-topology and vague convergence on the space of random measures. A proof of the Lévy-Ito decomposition using the Lévy-Khintchine formula, as well as Kallenberg’s Theorem are presented.
