自由乘性卷积的矩阵模型

Matricial model for the free multiplicative convolution

Guillaume Cébron

摘要:

本文研究了加法卷积和乘法卷积之间的Bercovici-Pata同态。我们还考虑了它们的矩阵形式,这些形式与埃尔米特矩阵空间和酉群上的测度有关。结合Benaych-Georges和Cabanal-Duvillard的矩阵模型,我们定义并研究了酉群上自由乘性Lévy过程的一个新的矩阵模型的大N极限.

英文摘要:

This paper investigates homomorphisms à la Bercovici-Pata between additive and multiplicative convolutions. We also consider their matricial versions which are associated with measures on the space of Hermitian matrices and on the unitary group. The previous results combined with a matricial model of Benaych-Georges and Cabanal-Duvillard allows us to define and study the large N limit of a new matricial model on the unitary group for free multiplicative Lévy processes.
