In this paper we introduce a general class of transformations of (all or most of) the class ML(Rd), of d-dimensional Lévy measures on Rd, into itself. We refer to transformations of this type as Υ transformations (or Upsilon transformations). Closely associated to these are mappings of the set ID(Rd) of all infinitely divisible laws on Rd into itself. In considerable generality, the mappings are one-to-one, regularising and bi-continuous. Furthermore, in many cases the transformations have a stochastic interpretation in terms of stochastic integrals with respect to Lévy processes.
