In this paper, we consider the specular reflective boundary problem for the onedimensional Boltzmann equation with soft potentials. It is shown that the solution converges to a global Maxwellian M+ under certain initial conditions. In order to prove this, we construct a local Maxwellian M¯ which is very close to M+ as an ansatz of M and obtain the stability of M¯ . Our proof is based on elementary energy estimates and detailed properties of Burnett functions.
