Abstract:
A class of upsilon transformations of Lévy measures for matrix subordinators is introduced. Some regularizing properties of these transformations are derived, such as absolute continuity and complete monotonicity. The class of Lévy measures with completely monotone matrix densities is characterized. Examples of infinitely divisible nonnegative definite random matrices are constructed using an upsilon transformation.
Keywords:
infinite divisibility, random matrices, Lévy measures, cone valued random variables, completely monotone matrix functions.
