Wave equation in the extreme Kerr black hole

Speaker: 臧云龙(扬州大学)

Abstract: Considering the massless scalar wave equation in the extreme Kerr geometry with the smooth initial data compactly supported outside the event horizon, an integral representation of the solution as an infinite sum over the angular momentum modes has been derived and then the solution of every azimuthal mode decays pointwise in time in L^{\infty}_{loc}.
