Transportation distance between the Lévy measures and stochastic equations for Lévy-type processes

Modern Stochastics: Theory and Applications
Preserved Fulltext
The notion of the transportation distance on the set of the Lévy measures on ℝ is introduced. A Lévy-type process with a given symbol (state dependent analogue of the characteristic triplet) is proved to be well defined as a strong solution to a stochastic differential equation (SDE) under the assumption of Lipschitz continuity of the Lévy kernel in the symbol w.r.t. the state space variable in the transportation distance. As examples, we construct Gammatype process and -stable like process as
