Hermitian Functional Representation of Free Lévy Processes
José-Luis Pérez G., Víctor Pérez-Abreu, Alfonso Rocha-Arteaga · 2015-11-11 · via math.PR updates on arXiv.org

A functional representation of free Lévy processes is established via an ensemble of unitarily invariant Hermitian matrix-valued Lévy processes. This is accomplished by proving functional asymptotics of their empirical spectral processes towards the law of a free Lévy processes. This result recovers a functional version of Wigner's theorem and introduces a functional version of Marchenko-Pastur's theorem providing the free Poisson process as the noncommutative limit process.
