报告摘要：We are concerned with the Cauchy problem on the Boltzmann equation in the whole space. The goal is to construct global-in-time solutions near Maxwellians with the perturbation admitting a polynomial tail in large velocities. The full range of both hard and soft potentials can be covered. The main difficulty to be overcome in case of the whole space is the polynomial time decay of solutions which is much slower than the exponential rate in contrast with the torus case.
