Abstract:
Abstract Inhomogeneous Lévy processes in topological groups, defined by independent increments, were introduced in § 1.4 . More useful representation of these processes may be obtained on a Lie group G. The main purpose of this chapter is to present a martingale representation, which characterizes an inhomogeneous Lévy process in a Lie group by a triple (b, A, η) of a deterministic path b t in G, called a drift, a matrix function A(t) and a measure function η(t, ⋅), in close analogy with the representation of a homogeneous Lévy process.
