内容摘要：

This talk concerns the thermostated Boltzmann equation with deformation, and the collision kernel includes both the Maxwell molecule  and general hard potentials with angular cutoff. We construct smooth steady solutions via a perturbation approach when the deformation strength is sufficiently small. The steady solution is a spatially homogeneous non Maxwellian state and may have the polynomial tail at large velocities. Finally, the long time asymptotics toward steady states are given.
