Different aspects of the milne problem (based on energy estimates)
Claude Bardos, Russel E. Caflisch, B. Nicolaenko · Transport Theory and Statistical Physics · 1987
We describe a method based on energy estimates for the study of the half space milne problem. To show the range of application of the method we start from the linear transport equation and we consider other problems (Including some short summaries of results described in companion papers). On the other hand, we do not consider classical or more explicit methods, which where introduced already long time ago. (cf. E. Hopf [17], or I. Busbrldge [18]).
