講　題：Boundary singularity  of  moments for the  linearized Boltzmann equation

摘　要：

We study the boundary singularity for  stationary solutions of the linearized Boltzmann equation with hard-sphere potential.  An asymptotic estimate  for the gradient of the moments is established, which shows  the logarithmic singularity near the boundary. Our formula holds for the solutions of the Milne and Kramers problems obtained by Bardos-Caflish-Nicolaenko, 1986. Our theorem requires the Holder continuity of the  boundary data. In particular, it applies  to the complete condensation problem for half space.
