Lévy processes are developed in the more general framework of semimartingale theory with a focus on purely discontinuous processes. The fundamental exponential Lévy model is given, which allows us to describe stock prices or indices in a more realistic way than classical diffusion models. A number of standard examples including generalized hyperbolic and CGMY Lévy processes are considered in detail.
