Abstract: We show $C^\infty$ local rigidity for a broad class of exceptional algebraic actions, including rank one partially hyperbolic actions,parabolic actions, higher rank but not genuinely higher rank partially hyperbolic actions.The method of proof is a combination of KAM type iteration scheme and representation theory and harmonic analysis. The principal difference with previous work that used KAM scheme is very general nature of the proof.
