## Communicated by H. Neunzert Stationary half-space solutions of the linearized Boltzmann equation are studied by energy estimates methods. We extend the results of Bardos, Caflisch and Nicolaenko for a gas of hard spheres to a general potential. Asymptotic behaviour is obtained for hard as well

β¦ Synopsis
A contraction mapping (or, alternatively, an implicit function theory) argument is applied in combination with the Fredholm alternative to prove the existence of a unique stationary solution of the non-linear Boltzmann equation on a bounded spatial domain under a rather general reflection law at the piecewise C ' boundary. The boundary data are to be small in a weighted L,-norm.

## Abstract The paper deals with the stationary Boltzmann equation in a bounded convex domain Ξ©. The boundary βΞ© is assumed to be a piecewise algebraic variety of the __C__^2^βclass that fulfils Liapunov's conditions. On the boundary we impose the soβcalled Maxwell boundary conditions, that is a co
## Communicated by V. Lvov Approximate solutions of the non-linear Boltzmann equation, which have the structure of the linear combination of three global Maxwellians with arbitrary hydrodynamical parameters, are considered. Some sufficient conditions which allow the error between the left-and the
## Abstract As a basic example, we consider the porous medium equation (__m__ > 1) equation image where Ξ© β β^__N__^ is a bounded domain with the smooth boundary βΞ©, and initial data $u\_0 \thinspace \varepsilon L^{\infty} \cap L^{1}$. It is wellβknown from the 1970s that the PME admits separable
