Summary: Approximate methods of solving boundary value problems of the theory of neutron transport, based on different ways of averaging cross-sections, are analysed. The methods of the theory of positive operators in Banach spaces with cones are used to establish the solvability conditions and properties of the corresponding solutions of linear and nonlinear conditional-critical problems which arise in the framework of such averaging.
