摘要：Connes rigidity conjecture for factors of PSLn(Z) provides a strong motivation to study invariants on this class of von Neumann algebras. Lafforgue/de la Salle rigidity theorem opens a door to harmonic analysis in this direction. In this talk, we shall present the first sufficient conditions for Lp-boundedness of Fourier multipliers in the group algebra of SLn(R)—in the spirit of Hormander-Mikhlin criterium for Euclidean multipliers—and a major strengthening of Lafforgue/de la Salle rigidity theorem. Joint work with Eric Ricard and Mikael de la Salle.
