摘  要:  After reviewing the progress on the Boltzmann equation without angular cutoff in recent years, I will present the result on the case when the initial data is a perturbation of a global Maxwellian with algebraic decay in the velocity variable. Global solution is proved by combining the analysis in moment propagation, spectrum of the linearized operator and the smoothing effect of the linearized  operator when initial data in Sobolev space with negative index.
