PS : Quentin Francois (Université Paris Dauphine) : A positive formula for the product of conjugacy classes on the unitary group
Bâtiment Fermat, salle 4205We describe with a probabilistic viewpoint the convolution product of two conjugacy classes of the unitary group 푈(푛). The description is given in terms of a probability distribution on the space of central measures which admits a density. Relating the convolution to
