The classical notion of Lévy process is generalized to one that takes as its values probabilities on a first or‐der model equipped with a commutative semigroup. This is achieved by applying a convolution product on definable probabilities and the infinite divisibility with respect to it (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
