A CLASS OF LINEAR KINETIC EQUATIONS IN A KREIN SPACE SETTING

Krein space methods are used to derive the unique solvability of a class of abstract kinetic equations on a half-space with accretive collision operators. At the same time a new proof is provided for the case of a positive self-adjoint collision operator. A Fokker-Planck type example is worked out as a new application
