Title：D modules and Representations
Abstract：It was commonly believed in the fifties that everything about the L^2 spectrum of a real reductive Lie group comes from the spectral theory of differential equations. I shall begin with the modern reincarnation of this : the Kashiwara pentagon (he recently got an ICM Chern medal and then the Abel prize). Then I descrribe the main theorem of Berthelot on Arithematic D modules and return to a few issues on the Kashiwara pentagon.
