Let X = (Xt , 0 ≤ t < ∞) be a Lévy process on the Euclidean space Rd , that is, a process on Rd with stationary independent increments which has right continuous paths with left limits. We denote by Px the probability measure such that PX(X0 = x) = 1 and by Ex the expectation relative to Px . The process is characterized by the exponent Ψ through
